A consistent composition with the addition of finely ground copper powder is called copper grease. In addition to basic tasks: reducing the coefficient of friction, jamming of mechanisms, anti-corrosion protection, copper grease has a unique property.
Threaded connections operating at high temperatures (up to 1000 °C) may boil. If fasteners are pre-treated with a lubricant containing copper, the effect of thermal curing is minimized.
To increase efficiency, finely dispersed copper is added to the grease with a thickener. Moreover, the particle size must be so small that it does not violate the basic properties of the lubricant. That is, the metal particles themselves should not be abrasive, so as not to become sources of increased friction.
Types of copper greases
Despite the similarity of the compositions, the lubricant is divided according to consistency and purpose. Consider the varieties on the example of popular compositions:
Other forms of consistency are practically not produced, there are only different packaging. It can be a jar, soft tubes (tubes), disposable bags or aerosol cans.
Specifications and Benefits of Copper Grease
The main parameters of the compositions (regardless of consistency) are formed based on the scope of application:
The use of copper lubricants in everyday life, cars, and in production
Regardless of the area of \u200b\u200buse, you need to remember some rules:
- thorough cleaning of treated surfaces: mechanical and chemical;
- removal of corrosive deposits: the lubricant is not a rust converter; under its layer, the foci will spread further;
- be sure to remove old grease and other compounds to prevent unwanted chemical reactions;
- areas of the surface that can accidentally get grease must be shielded: especially when using an aerosol;
- excess thickness does not need to be removed.
Where copper grease is used - video
Due to its unique properties, copper grease can be used not only in car mechanisms and special equipment.
- Foundries: all the way to the processing of fixtures and hinges for molten metal containers as well as moulds.
- Metallurgical enterprises: rolling plants, forging mills, presses for hot forming of metal. The only limitation is that copper grease is not applied to high speed shafts and bearings.
- Refineries: sealing flanged joints exposed to aggressive petrochemical attack.
- Mining industry: Copper grease for drill rods has almost no substitutes.
Features of application in the brake system:
Lubricant for calipers is used only in accordance with the instructions. A common mistake is applying the same compound to the back of the pads and caliper guides. 
Not all formulations are universal in this area. In fairness, we note: in other cases there are no restrictions on the use (within the framework of common sense).
First principle: a reasonable amount. From a marketing point of view, the larger the capacity, the lower the cost per unit of volume. Therefore, car services acquire such trains in 3-10 kilogram cans.
For garage use, this amount is not needed, the maximum consumption weight: 300-500g. Many car enthusiasts buy small tubes or disposable bags for one-time maintenance.
This seems logical. But if you compare the prices on the counter, a half-kilogram jar may not cost much more than a 150-gram tube. 
Paste or spray? Despite the obvious ease of application, professionals do not recommend the use of aerosols. Unless for processing large areas. The quality of the grease application is still better.
The only drawback of the paste is that it is difficult to control the consumption.. Aerosol is more economical (at the same time, the cost of such packaging is higher). There is no point in discussing the logo on the packaging. Any manufacturer producing lubricants in accordance with GOST or TU will provide the same product quality.

Copper grease is a substance for use in the braking system of a car. What is this lubricant for? She is lubricated with calipers - elements for attaching brake pads. With the help of a caliper, the brake pads are pressed tightly against the brake disc, thereby ensuring safe braking. Also, this lubricant prevents failures in the brake system at high speeds.
Copper grease for guide calipers must be of exceptionally high quality, since the brakes are responsible for the safety of everyone in the vehicle. A car may be driven with a dented body or a cracked headlight, but with a faulty brake system, no car should be driven as this is fatal.
How to choose the right lubricant?
1. The grease must withstand high temperatures, from 180°C or more. This is due to the fact that the brakes work in super-heavy conditions and constantly heat up. The friction between the disc and the pad sometimes reaches 500-600°C. The surface of the remaining components of the caliper is heated up to 150°C. This happens when driving hard or in extreme situations, such as driving on winding, icy roads.
2. The substance must not melt or flow when overheated.
3. Grease must not dissolve in water and brake fluid. It must be resistant to moisture and other chemicals. This is due to the fact that the components of the caliper are constantly in contact with water when driving on the highway. In winter, salt and other chemicals are added to the moisture, which are sprinkled on the roads. Also, the caliper is in contact with the contents of the brake system.
4. The lubricant must not corrode the plastic components and elastic seals of the caliper. This applies to a greater extent to rubber, the basis of which is a copolymer of ethylene, propylene and a diene monomer, as well as an ethylene-propylene copolymer (EPT). These chemicals are most commonly found in plastic caliper parts.
The chemical composition of lubricants
Most often, they include three basic components: fine copper, anti-corrosion agents, synthetic or mineral oils. Their task is to prevent jamming of the mechanisms of the brake system. Some lubricants are diluted with graphite or aluminum powders, in which case it will be copper-graphite or. Sometimes manufacturers produce caliper lubrication paste with a thick consistency, as this prevents the lubricant from escaping from those parts that do not fit snugly together.
Copper grease for calipers is an excellent layer that protects parts from friction and overheating. Lubricants protect parts of the caliper from carbon deposits, moisture, corrosion, cover the parts with an even layer, and can serve for a long time without needing to be replaced. They also resist the influence of acids, alkalis, salts, almost do not evaporate and do not have a dew point. Due to their chemical composition, lubricating masses are good conductors of electrical impulses that are supplied to reduce the friction force in mechanisms.
Lubricant classification
Lubricants are divided into three groups:
●Lubricating mixtures for metal surfaces designed for high temperatures. The basis of these mixtures are mineral or synthetic components based on oils and a thickener. Most often they are produced with copper, graphite, aluminum impurities of molybdenum disulfide in the form of a fine powder. At very high temperatures, micropowders come into play. Some greases are made without the addition of metal powders. Used for calipers, and other connections.
●Lubricants for fastener edges, seals and bushings. They are produced on the basis of oils with a mineral base, clay is most often used as a thickener. They are characterized by the fact that, under the influence of high temperature, leaks from loose fitting parts are excluded.
●Lubricants suitable for all moving parts of the mechanism, including plastic and elastomeric parts. Used in cars, trucks and buses. Depending on the addition of powders, the metals have a different color. No dropping point.
What kind of copper grease to buy?
Before you make a purchase, you need to know what types of copper lubricants are on sale. Their composition depends on the application. A copper spray lubricant is produced, and a copper spray lubricant is also often seen on sale. Where it is necessary to lubricate loose parts, copper paste grease is used to prevent leakage.
Spray or aerosol lubricant is a copper aerosol lubricant that is sprayed onto parts from a pressurized can. It is most often purchased for threaded connections, as well as parts that are under the influence of strong heat, corrosion processes, and high pressure. It is used to lubricate the brake system, compressors, turbines, exhaust system and spark plugs. The basis of the lubricant is copper. It is applied in branch of chemistry and petrochemistry, in the automobile - and mechanical engineering.
Synthetic type brake lubricant is a high heat paste containing ceramics. It is characterized by an increased level of adhesion, well resists salts and moisture. After treatment of the brakes, it protects them from squeaks and other noises between the support, brake pad and lining. Optimizes the performance of the brake mechanism, which after lubrication becomes much more reliable. If you need lubrication for calipers, disc and drum brake elements, as well as for fasteners, we recommend that you pay attention to Kupferpaste (Kupferpaste) from Divinol.
Lubricated with the addition of aluminum - prevents seizing of elements at elevated temperatures. It also protects parts from cold welding due to heavy loads, sudden movements. Eliminates the manifestation of vibration when sliding. It does not make it possible to stick to the components of the exhaust manifold, bolts on the wheels. Suitable as a release agent for parts under superheating and overload conditions. Relieves parts of brake systems from vibrations and the sounds they create. Resistant to sudden changes in temperature, corrosion, has excellent anti-seize properties. Reduces friction, wear of parts, makes it easy to disassemble the elements of mechanisms after a long period of use.
Pasta prices
The price of copper spray grease is set by the manufacturer. Unfortunately, domestic manufacturers cannot boast of a large assortment of this product. The quality also leaves much to be desired. Such lubricants can be bought for VAZ cars. They do not require such care as foreign cars, so domestic lubricants are also suitable for them.
For foreign cars, it is better to buy high-quality lubricant, especially for lovers of high-speed driving. If this is about you, then the Divinol brand is the perfect choice. The faster the car develops, the better the lubrication should be, because the higher the speed, the more heat the brake system is exposed to.
What are the main requirements for an aluminum anti-seize lubricant?
Such a lubricant is called a separating lubricant and its main purpose is to ensure reliable separation of parts that come into contact with each other with great effort, at high temperatures and under the influence of aggressive media, for example, road reagents. At the same time, the mutual movement of parts itself can be very small (brake shoe and caliper) or absent altogether (wheel studs and nuts). Demands follow from the purpose.
First: the lubricant must work reliably at high temperatures, it must not thin out when heated and flow out of the contact zone of the parts. Cheap imitations sin with this when aluminum powder is mixed, for example, with Litol, and they pass it off as a real lubricant. When heated, Litol flows out, washing away the powder with it, and such a “lubrication” stops working. In a high-quality lubricant, the base does not flow during any heating up to burnout, and even when it starts to burn out, it leaves all the aluminum in the contact zone, which continues to play the role of a release lubricant.
Second: high adhesion to metal is required. Adhesion can be checked with a fairly simple test. Apply lubricant to a smooth, clean metal surface and wait 15-20 minutes for the solvent to evaporate. Then try to wipe off the grease with your finger. If the grease is peeled off to the metal, it is unusable, if the finger slides over the grease, but does not remove it from the surface, everything is in order.
Third, since the grease is constantly exposed to the weather, it must not be washed off with water.
Do I need to prepare the surface before applying the lubricant?
Since one of the requirements for aluminum grease is high adhesion to the surface, the grease must be applied to a clean, grease-free surface. To do this, you can use AXIOM Brake and Clutch Cleaner or AXIOM Quick Cleaner before application.
Is it possible to judge its quality by the appearance of the applied lubricant?
By the appearance of the applied lubricant, one can partly assess its quality. A good lubricant should lay on the surface like paint, creating an even layer of silvery color on it without visible disintegration into fractions. If the lubricant falls unevenly, even with a thin layer it starts to flow, this indicates its low quality.
What is the difference between aluminum grease and copper grease?
There are no fundamental differences between them - both aluminum and copper lubricants are designed to prevent parts from “seizing” among themselves, and in most cases are interchangeable. The exception is cases where copper can cause electrochemical corrosion of lubricated parts - then it is necessary to use aluminum grease. Also, sometimes aluminum grease is preferred to copper grease for aesthetic reasons, for example, if the brake calipers are silver and you don’t want to “dirty” them with copper.
Lubrication for calipers and guides makes it easier to operate parts of the brake system, as they work in difficult conditions. There are several types of lubricants. We will try to systematize the information and answer a number of questions of interest to car owners.
Types of lubricants
In particular, we will deal with the following topics:
Types of lubricants
It is worth pointing out right away that manufacturers divide the lubricant into two types - paste and spray. Before moving on to listing their types and brands, it is necessary to decide what characteristics the caliper lubricant should have. With an aggressive driving style or driving along mountain serpentines, the temperature of the caliper can reach +300°С, and in urban conditions it can warm up to +150°С...200°С. In addition, the caliper is affected by moisture, dirt, reagents that are sprinkled on the road. Therefore, the lubricant for calipers and its guides should be:
- non-aggressive towards rubber and plastic parts of the machine;
- not lose their properties when exposed to water, brake fluid or other substances that can wash or dissolve it;
- , that is, do not lose their temperature properties at + 180 ° C or more;
- should not lose its physical properties during significant frosts (from -35 ° C and below).
Commonly used cheap lubricants do not provide the described conditions. We are talking about graphite paste, lithol, nigrol and their other analogues. That is, for the normal operation of the brake system, and in particular the caliper, it is necessary to use modern developments.
Currently, manufacturers produce the following groups of lubricants for calipers:
First group - mineral or synthetic pastes using metals. They are of the type high temperature extreme pressure. Their operating range is very wide, and is approximately -185°С...+1100°С(each grease has its own operating range).
The substance is based on synthetic or mineral oil, to which thickeners are added, as well as metal particles (copper or molybdenum). This includes the following subtypes:
- complex pastes, which include powder of copper, aluminum and graphite;
- copper, having in its composition a powder of copper and graphite;
- pastes without metal particles, instead of which magnesium silicate and ceramics are used;
- lubricants based on copper or molybdenum disulphide.
Examples of specific brands of lubricants of this type:
- complex pastes- HUSKEY 2000 Lubricating Paste and Anti-Seize Compound for High Temperature, Loctite #8060/8150/8151, Wurth AL 1100;
- copper pastes- HUSKEY 341 Copper Anti-Seize, LIQUI MOLY Kupfer-Paste, Mannol Kupfer-Paste Super-Hafteffekt, Marly Cooper Compound, Molykote Cu-7439 Plus Paste, Motip Koperspray, Permatex Copper Anti-Seize Lubricant, Pingo Kupfer-Paste, Valvoline Cooper Spray, Wurth SU 800;
- metal-free pastes- HUSKEY 400 Anti-Seize, TEXTAR Cera Tec, LIQUI MOLY Bremsen-Anti-Quietsch-Paste;
- molybdenum disulphide pastes- HUSKEY Moly Paste, Assembly Lubricant & Anti-Seize Compound, Loctite #8012/8154/8155.
Pastes belonging to this group can be applied to the GUIDE PINs of brake calipers and any highly loaded friction surfaces, except for the working surfaces of the brake pads!
Second group - Mineral oil based pastes. They include bentonite, which acts as a thickener. In addition, metal particles and fatty acids are added here. The main advantage of a mineral-based lubricant is sustainable work in the temperature range from -45°С...+180°С. That is, the paste does not flow out and does not lose its properties. Thus, it is excellent for lubricating guide calipers in cars operated in gentle conditions. An example of this type of grease is Teroson VR500.
Third group - synthetic oil based lubricants. This is the most universal formulations, since they are suitable not only for lubricating calipers, but also for other elements of the car's brake system. Lubricants are made from refined synthetic oil, as well as additives that have anti-corrosion, anti-oxidation, anti-wear properties. It also contains a thickener. Synthetic oil based lubricants have excellent characteristics. They do not dissolve in water, brake fluid, alkalis and acids, do not evaporate, and also have dielectric properties. The operating temperature range is approx. -40° to +300°С.
Examples of lubricants are Molykote AS-880N Grease, Permatex Ultra Disk Brake Caliper Lube, SLIPKOTE 220-R Silicone Disc Brake Caliper Grease and Noise Suppressor, SLIPKOTE 927 Disc Brake Caliper Grease.
The scope of their use is wide. They are used for the lubrication of sliding and rolling bearings, as well as other parts operating under conditions of high temperature and significant pressure.
One of the most popular types of pastes and sprays for calipers and guides are copper greases, which are a type of grease that uses metal. Let's dwell on it briefly.
Copper grease (high temperature)
She, like other lubricants for calipers, belongs to the high temperature. That is, they are able to withstand significant temperature overloads during the operation of the brake system.
Copper greases consist of three main substances - crushed fine copper, oil (mineral and synthetic), as well as some substances that are designed to resist corrosion. Lubricants are sold in the form of a paste or spray. They have a high viscosity, so penetrating into the gaps, they do not flow out.
Benefits of Copper Lubricants lies in wide operating temperature range, reduction of friction forces, no evaporation and dew points. If you decide to use copper grease, you must be sure to follow the conditions for its application. First, the working surface of the part must be thoroughly cleaned. Secondly, grease must be applied carefully so that debris does not get on the part with it. Thirdly, excess grease does not need to be removed.
If the caliper of your car is made of aluminum, then copper grease cannot be used, because contact corrosion of aluminum will occur (since these two metals are “not friends” with each other)
Overview of lubricants for calipers and guides
Molykote Cu-7439 Plus
Molykote Cu-7439 Plus. Manufactured in the United States, made from fine copper powder and semi-synthetic oil. One of the most popular and currently in demand lubricants for calipers, since its advantages include:

XB40019 XB40019 for Hado VeriLub Lithium Multi-Purpose Spray Grease.
SLIPKOTE 220-R DBC
SLIPKOTE 220-R DBC(Silicone Disc Brake Caliper Grease and Noise Suppressor). Also an excellent lubricant for calipers, and interestingly, it also has a permit for use in drinking water systems. According to the reviews of many motorists, this is one of the best pastes for lubricating guides. However, for many, the difficulty lies in its purchase. The optimal solution is an order from abroad. Temperature operating range - -46 to +299°С. It is based on refined synthetic oil, a thickener and additives that give it anti-corrosion, anti-oxidation and anti-wear properties.
The manufacturer supplies lubricants under the SLIPKOTE trademark to automotive plants. In retail, products are sold by Pennzoil, Loctite, Permatex, TRW Autospecialty, Toyota. According to the catalog, for ordering, it goes like HUSKEY 72983 or if Toyota, then 0888780609. With all the advantages of the lubricant, it has the only drawback - a high price. One tube weighing 85 grams will cost you about $20.
Note! On vehicles with drum brakes, SLIPKOTE 220-R DBC must not be used. In this case, for example, Huskey 2000 Anti-Seize can be used.
LIQUI MOLY Bremsen-Anti-Quietsch-Paste
LIQUI MOLY Bremsen-Anti-Quietsch-Paste, this lubricant NOT RECOMMENDED you to enjoy. Despite the temperature characteristics declared by the manufacturer - -40°С...+1200°С, it has a number of disadvantages. The fact is that initially it was really positioned as a lubricant for caliper guides. However, after some time, consumers began to have problems caused by its operation. And the manufacturer decided to downgrade its status to anti-creak. Even on the official website there is information that “It is not recommended to use calipers and anthers for lubrication of guide pins.” However, at present, many online stores and unscrupulous sellers, unknowingly or on purpose, continue to sell it as a caliper lubricant. But this does not mean that Liquid Moli does not have good lubrication for calipers, other models have proven themselves quite well.
What is the best grease for calipers?
Let's summarize what kind of lubricant for calipers is best to use. When choosing, you must be guided by the following considerations: the operating conditions of the car, the wear rate of the brake system, the brand of the car, the price of lubrication.
If you own an average car and have a moderate driving style, then it makes no sense for you to overpay and buy expensive lubricants. For example, buy the now popular Russian brand MS-1600 or XADO Very Lube caliper lubricant.
Caliper Grease Temperature Test
If you own an expensive car, or subject the braking system to significant loads (you race, ride in the mountains), then it makes sense to buy a more expensive lubricant. For example, Slipkote® 220-R DBC or Molykote Cu-7439 Plus. They work in a wide temperature range and reliably protect the caliper and the brake system as a whole. Therefore, often the decisive factor in the choice is the price. We hope that the reviews below on some brands of lubricants will help you make your choice.
Caliper Lubrication Reviews
Having collected tips and real experience in using popular lubricants by car owners, we provide reviews based on which you can evaluate all the advantages and disadvantages of each of them.
Slipkote 220-R DBC
Molykote Cu-7439 Plus
XADO Very Lube
| positive | Negative |
| A good thing. The only drawback is that you need to apply several layers on the caliper guide. | I didn't like her very much. After application, after a while it becomes very thick, after a couple of months it begins to coke, and the movements of the caliper become difficult |
| For guides and caliper cylinders under the anther, that's it. Only need to be applied in layers with an interval of 2-3 minutes 2-3 times | Grease full "G", money down the drain |
| I have been using XADO grease without exaggeration for probably 150 thousand already… no problems… | For guides, it is categorically not suitable |
| Someone writes that VeriLub is "shit", but I'm satisfied. I started lubricating it with it after 10 thousand runs, now it’s already 60, everything is normal. I have been using a VeryLube balloon for 3 seasons (~ 6 replacements) and there is still a lot (Logan car) |
MS1600
| positive | Negative |
| Normal feeling of lubrication. I liked that the creak immediately disappears. | The declared characteristics are doubtful, the lack of international approvals. |
| I tried the MS-1600, it is inexpensive and the quality suits. After changing the pads again and using this lubricant on the guides, the pads finally began to grind evenly. | She is very thick. Stuffed ms 1600 into guides. In winter, uneven wear of the pads began - the inner one was worn down more than the outer one. The grease dried up in a year and turned literally into dark gray plasticine. And under the anther of the piston dried up completely. I would not advise using it as an anti-creak one either, in the reviews I found more than once that people complain about the return of creaks. It is better to have several good proven specialized lubricants for a particular assembly than to have one universal |
The use of innovative lubricants not only extends the life of the equipment, prevents seizing, but also improves the quality of its operation, increases efficiency and reliability. The modern market offers a variety of lubricants in an assortment, however, without certain knowledge and skills, it will be quite difficult to choose the optimal type for mechanisms and assemblies operated in high-temperature and high-load conditions.
Copper-based pastes and greases for high temperatures: features and scope
Copper greases are in demand in various industries and have a wide range of applications, they have proven themselves in the best way:
- in food;
- in the automotive industry, incl. at tire shops (for lubricating brake pads, brake mechanism, processing threaded connections, guides, wheel bolts, calipers)
- in the petrochemical industry;
- in metallurgical;
- in foundries, for processing a wide variety of compounds;
- in the construction industry, etc.
Indispensable copper extreme pressure lubricants when processing all types of metal threaded connections, sliding surfaces, terminals, flanges, nuts and bolts, hydraulic components, hubs, brake shoes, as well as many other parts that require protection against corrosion, seizing, abrasion. Regular use copper lubricants high-temperature ones will extend the service life of shut-off valve parts, stuffing boxes, rolling bearings, hinges, flange joints, as well as other equipment operated in extreme temperature conditions, and protect components from steam, carbon deposits, and soldering.
Their popularity is explained quite simply:
- designed to meet the upcoming loads - high pressure and high temperatures;
- retain properties in a wide temperature range - from -50°С to +1100°С;
- work with various surfaces - steel, cast iron, aluminum, bronze, nickel and brass,
- provide reliable protection when exposed to water, salts, weak acids, alkalis and their solutions;
- lubricant is used at temperatures up to 1100 degrees;
- cover parts evenly, with a thin layer, do not require replacement for a long time.
Features and Benefits of Using Copper Lubricants
Copper pastes and lubricants provide electrical conductivity and reduce friction, are slowly washed out and evaporate, reduce vibration during operation of the equipment, besides, they do not contain lead, and are indispensable for processing threaded connections.
Of the main advantages of innovative copper-based lubricants, the following should be highlighted:
- simplification of assembly and installation - the tightening force of threaded connections remains constant, which is important, for example, for the exhaust system;
- easy dismantling of connections, as well as sliding and pressure areas, even during their continuous operation;
- increased load-bearing capacity - prevent seizure and scuffing of the surfaces of the hubs;
- have excellent hydrophobic properties and high adhesion with various types of surfaces;
- reliably protect details from metals and alloys from corrosion;
- increase the tightness of the joints.
- prevents seizing under high loads of non-working surfaces of brake pads,
Application features
The best copper grease- This is a well-chosen and correctly applied product. In order for this lubricant to cope with the functions assigned to it, when using it, follow a few simple rules recommended by many experts:
- all surfaces should be thoroughly cleaned before applying copper paste - remove dust, residues of previous lubricants, dirt;
- apply the products with a brush or a piece of cloth;
- lubricants have capillary properties, so the composition perfectly penetrates into holes and crevices, excess lubricant can not be removed.
Solution buy copper grease high-temperature - this is an opportunity to provide reliable protection to mechanisms, assemblies, parts and elements from friction and overheating in a fairly wide temperature range, increase their overall service life and extend the period of trouble-free operation.
How to choose and buy copper grease?
Under the name "copper paste" they often sell lubricants in aerosol cans and pastes. Before buying, decide what you need it for.
For the treatment of non-critical threaded connections, sprays can be used to protect the threaded part - it is convenient to apply them, the consumption is small. Copper sprays are used to treat exhaust systems, brakes, and spark plug connections. The main anti-friction component of such sprays is copper. A copper-based lubricant must resist moisture penetration, withstand high temperatures and aggressive environments, all of which prevent threaded connections from seizing. Low temperature copper grease must be based on synthetic oil.
Aerosols are mainly used in automobiles and medium mechanical engineering where they are used to treat gaps between fasteners, brake pads, etc.
To protect important components from high temperatures, it is better to use pastes - in addition to copper powder, they include a complex of additives: anti-friction, anti-oxidation, extreme pressure and, importantly, a corrosion inhibitor (provides reliable protection against corrosion). The use of copper pastes improves the ability of the mechanism to withstand the effects of moisture, electrolyte, makes it possible to increase the electrical conductivity of the connection, prevents jamming, and stabilizes electrical impulses.
If you are looking for a copper universal grease for calipers, fasteners, for processing threaded connections, you can use Storm-1000 - more detailed information about the product is available at the link: high-temperature copper grease Storm-1000 - this material has a wide range of applications, often this consumers purchase lubricant to replace liqui moly.
Numerous tests of domestic products on ChShM and real industrial sites have demonstrated the beneficial effect of the created metal cladding film on minimizing scuffing on working surfaces and reducing the overall wear of the contact layers. The greatest effectiveness of the lubricant compositions "Storm-1000" and "Polykont", developed on the basis of copper-containing composites, in terms of improving tribological and rheological characteristics and increasing the interval between lubrication is achieved with increased static loads (P ≥ 600 N) and with intensive high-speed mode.
Accordingly, they are most effective for equipment and units operating in extreme and harsh conditions.
The use of copper grease reduces friction, protects metal surfaces from seizing, prevents wear of parts, ensures easy dismantling even after prolonged use, allows the connection to withstand heavy loads by reducing friction, and withstand high temperatures. Lubrication should be applied to a well-cleaned friction unit, this will extend the life of both the lubricant and the unit itself.
When buying copper greases and pastes pay attention to the base oil - synthetic will provide a longer service life compared to mineral, and the presence of a corrosion inhibitor in the composition will prevent the destruction of the part when interacting with aggressive environmental components.
Copper high-temperature greases from Interauto allow you to completely replace imported copper heat-resistant greases from German or American manufacturers, which makes it possible not to use special OEM greases.
Copper pastes for threaded connections
Threaded connections during operation are often subject to thermal-oxidative and atmospheric corrosion, with a long-term corrosion process, the threads can be completely deformed and lead to the impossibility of dismantling without destroying both the threaded pair and the assembly itself. This entails an increase in the cost of repair work and an increase in their duration. High-temperature copper paste Storm, due to the content of an effective corrosion inhibitor, allows you to protect friction pairs from ordinary steels and ensure trouble-free disassembly of joints even after several years after assembly. However, for stainless steels, we recommend using a ceramic-based thread paste - Storm-1000F modification - it will ensure the disassembly of the assembly even at operating temperatures above 1500 degrees. Despite the higher cost, this paste is more effective on nerve steels and titanium alloys.
Copper lubricants as a means of minimizing the surface destruction of metals during friction
Metal cladding lubricants containing ultra-dispersed powder of such a soft metal as copper are the most effective products for servicing the movable interfaces of mechanisms and machines. At the same time, having excellent rheological properties and high bearing capacity, copper grease counteracts the transmission of vibrations and the occurrence of extraneous sounds, quickly forms a servovite film and effectively removes excess heat from the friction zone. The synergistic interaction of copper-containing modifiers and the thickener realizes the effect of wearlessness during rolling and sliding friction, since due to the segregation of copper and iron clusters, the microscopic loss of steel particles on rubbing surfaces is compensated and wear is largely ordered.
The mechanisms of the lubricating action of copper-containing products exclude the participation of metal particles in the formation of boundary layers. Interacting with tribochemical oxidation products and optimizing additives, copper particles block the access of oxygen molecules to the friction zone, as a result, oxidative and destructive processes are minimized on the surface layers of metal parts. It also eliminates seizure and welding of mating parts, even for such highly loaded parts as exhaust manifold pins, wheel bolts of road and rail transport. The main advantages of materials from this group include the ability to concentrate shear deformations in an ultrathin contact layer and resistance to point overheating. Copper greases not only reduce the wear of working surfaces, but also minimize mechanical and energy losses in friction pairs, which is especially important for heavily loaded units and high-speed mechanisms. They perfectly seal joints and are perfectly kept in open knots.
At the same time, copper grease has very high adhesion and strength under centrifugal loads. Due to this, it perfectly seals and resists dropping, washing out and extrusion, therefore its use is justified and expedient in threaded connections, screw pairs and in heavily loaded low-speed units. It also shows high resistance to salt and hot water, including under pressure, which helps to reduce atmospheric and chemical corrosion and expands the scope.
The study of friction surfaces confirms the effectiveness of copper-containing lubricants at loads above 600 N, and when exposed to less than 200 N, as anti-wear products, they become ineffective. The microstructure of the surface layers treated with such compositions undergoes significantly less destruction and changes even under the influence of high temperature than when using conventional anti-friction and extreme pressure lubricants.
But not every copper grease has the above advantages. This is due to the fact that salt compounds containing copper, in contrast to the pure substance Cu, negatively affect the chemical stability of the lubricant, both during dynamic processes and during long-term storage. Responsible manufacturers compensate for these shortcomings by introducing original and effective antioxidant additives. Other rheological and physico-chemical properties are improved by the same method. Therefore, copper greases can differ significantly in their intended purpose, performance and operating temperatures. So Kupfer paste is the most effective for processing brake pads and withstands extreme temperatures, and the Shtorm-1000 lubricant produced by Interauto, due to the synthetic base, is efficient in the range of -60 ÷ 1000 ˚С of the base and is a universal product.
Its use is justified in the movable and fixed parts of the molds of casting machines and in fasteners and threaded connections, but most often it is used for exhaust manifold studs, wheel bolts, nozzle heaters.
Compared to graphite lubricants, it is more effective and perfectly prevents sticking of exhaust manifold studs, setting of fasteners for thermal installations, threaded elements of casing and drill strings, compressor and ventilation units.
