How to choose wheels? Alloy wheels What alloy wheels are made of.

Currently, the most common type of alloy wheels for a car are just alloy wheels. They are the most popular among motorists not only in Russia, but also abroad. Given that they are produced in large quantities, you can find high-quality and fake copies on the market. Among the advantages, it is advisable to note the rather low cost of these products.

About how they are made

It is easy to guess by the name of this thing how exactly they are made. The raw material is simply poured into the prepared mold. The most commonly used alloys of metals based on aluminum. Magnesium-based specimens are extremely rare in practice. Alloy wheel types for cars are distinguished by good performance and wear resistance.

It is noteworthy that they are more resistant to impacts than their steel counterparts. In general, the strength characteristics of rims for a car of this type can depend largely on the quality of the raw material, as well as the shape and quality of the finish and paintwork. From this we can conclude that it is not worth buying the cheapest alloy wheels for a car, since their quality will be minimal.

The main differences between cast disc types from the rest

Which wheels are better steel or alloy? This question is often of interest to novice motorists, but soon everything becomes obvious. Alloy wheels for cars are lighter in weight and differ in technical characteristics, strength and aesthetic qualities.

It is noteworthy that cast types of car disks are on average 40% lighter than their steel counterparts. This not only improves the quality of car handling, but also manages to minimize the load on the suspension.

Visually, alloy wheels for cars look very attractive, so young people often prefer this option. As you can see, there are a lot of advantages, and that is why the price for one cast disk can differ several times from the cost of a steel counterpart.

Not only weight plays a decisive role here. There are many differences that can manifest themselves directly during the operation of the vehicle. For example, when the casting is completed, the disks will be subjected to a heating procedure, which will allow the product to achieve maximum strength and rigidity. Many people know that light-alloy types of disks for cars do not bend with a strong impact, but immediately split.

Cast rims and off-road

Alloy wheels for a car can have different properties that you should pay attention to. Marking may indicate types, size, manufacturer and other information. On off-road, alloy wheels of a car show themselves perfectly, but a lot depends on the quality of the product. The size is also important, that is, the larger the diameter, the greater the clearance of the car.

Wheel alloy wheels are fundamentally different only in that, unlike the steel counterpart, when hitting pits, they burst, and they bend. If deformation takes place, then the tire will gradually lower. Provided that high-quality raw material has been used, alloy wheels perform well off-road.

Now imagine what will happen if you fly into a deep hole at high speed? Of course, nothing good will come of this. Whatever the size of the rim, it will be severely damaged. Many garages offer remanufacturing, but these rims are by and large unrepairable.

Through welding and painting, it will not be difficult to restore this thing to its original appearance, but technical indicators cannot be restored. Do not assume that alloy wheels are inferior to steel ones, as this is not at all the case. They just aren't without flaws. The minimum weight and the ability to install even on old cars are considerable advantages. In fact, a car with them becomes really safer, and handling increases significantly.

When should you not use cast rims for a car?

In general, they can be used in all situations. The only thing is, if the rim size is not suitable for a particular car, then you should not install it. Among the advantages of using them, one can note the minimum weight, as well as the ability to abandon the constant use of caps, which are endlessly lost. In addition, alloy cast rims have an attractive aesthetic appearance and can serve as a car decoration.

At the stage of purchase, you need to look at what markings are on certain rims, and if you have any questions, then in such a situation it makes sense to contact the seller to provide them with advice. If you often drive outside paved roads, then you should not give preference to cast wheels, as this choice will not be justified.

Wheel rims of an alloy look will not suit all lovers of aggressive driving.

If you have already chosen them, then in this case you should drive through railway intersections and other obstacles as carefully as possible, even if you are sure that the manufacturer used high-quality raw materials.

Features of operation in the winter

Alloy wheel types are suitable for use in winter, but each motorist must choose them according to preferences and driving conditions. Chunks of ice and frozen dirt will constantly threaten to hit the side of the rim with hard blows. Marking will allow you to understand at the selection stage how strong this or that instance is, but with a strong impact, all of them can be damaged. The car will only handle well if the rims are in good condition. If you have never driven a car in winter before, then you should not choose a large rim size, as this will impair handling.

Substances that are sprinkled on roads in the winter season negatively affect the paintwork of not only the body, but also the wheels. Cosmetic restoration can be quite expensive. If the car itself is quite heavy, then it makes sense to use cast wheels, the weight of which is minimal, and the size and markings are suitable for the particular car model chosen.

Please note that in the winter season it is much more advisable to use types of tires with a high profile, since only they can protect your expensive alloy wheels for a car from mechanical damage. The diameter marking must always correspond to the minimum allowable value for a particular car if it is operated in winter.

Conclusion

So now you know what alloy wheels are, how they differ from their steel counterparts, and when to use them. At the stage of purchase, you should not look only at the appearance of the product and its weight, as it can be deceiving. It is preferable to choose really high-quality, but more expensive copies, the weight of which is much less than fakes.

Now you will not surprise anyone with alloy wheels on a car. But for several decades it was a luxury. They were very expensive and not everyone could afford them. But progress does not stand still and gradually such products flooded everything and everything. Yes, and it seems to me that they even began to crowd out the usual “stampings” (here they chose which ones are better). But how they are made, many do not know. Our article today will reveal this secret to you ...

Alloy wheels are crowding out ordinary ones because they are more aesthetic (beautiful), lighter (which has a positive effect on consumption and load on the car's suspension), and there are thousands of different shapes and colors. And now about the production itself.

From the name it is clear that they are pouring. Usually made of aluminum and magnesium alloy. It is the alloy of these materials that makes the disc the most durable to mechanical damage. Previously made only from aluminum, such options were not very durable, so they often broke (burst), which negatively affected their reputation. Due to the fact that they were made of aluminum alloy, in many countries they were called “aluminum”. However, then, in order to give rigidity and resistance to damage, magnesium was added to the aluminum alloy. This gave reliability, now to break a modern disk, you need to try. However, there are professionals here too!

So, the production process itself begins with ingots of metal (aluminum and magnesium) in the right proportion. Which are laid in the oven and heated to 600 - 700 degrees.

Heated alloy up to 600 degrees

At this temperature, the metal melts. And it is poured into special prepared forms, which already have the appearance of a finished product, but this is not yet a processed blank, after which it is cooled in water, which gives it rigidity.

almost finished form

But in order for it to get final rigidity, it needs to be heated several times, and then cooled, this happens at temperatures of 150 - 200 degrees. And here the disk is already cooled in air.

The next step is "turning". A cast hardened blank needs to be turned and machined to a shape with the correct dynamic performance.

Turning process

The blank is fixed on a special stand, where special cutters walk along it, which walk along the form, removing the fresco. After this processing, the disc is ready for use. It is packaged and delivered to stores and car dealerships.

It should be noted that such production is practically waste-free, the chips that were removed from the disk can be remelted and used in the production of other batches.

And now a short film that goes into detail about the production, literally five minutes of your time.

That's all, I think I've told you everything in detail.

The problem of choosing between steel and alloy wheels continues to cause a lot of controversy among motorists. Manufacturers add fuel to the fire by advertising their own products in every possible way for the purpose of sale. Therefore, stereotypes have formed about the characteristics of products made from different metals that do not correspond to reality. Hence the purpose of this material is to tell how stamped, forged and alloy wheels differ, how to distinguish them from each other and which ones are better suited for different operating conditions of a car.

Light alloy wheels

The name "light-alloy" was given to these products because of the properties of the materials from which they are made. This is an alloy of light metals - aluminum and magnesium, for strength and ductility, titanium and copper are added to it in small quantities. Hence the second name of such discs - titanium. There are 2 types of light alloy rims:

• cast;
• forged (pressed).

These 2 groups of products differ from each other in manufacturing technology, performance properties and cost. To understand which of them is better, you need to consider the production of discs in more detail.

Note. Sales representatives often impose on motorists the opinion that, unlike cast products, forged rims are made from incredibly strong and expensive metals, almost from platinum. In fact, this is a myth, the composition of the alloy for the manufacture of both groups of products is exactly the same. Manufacturers can slightly change the ratio of basic and additional metals in the melt at their discretion.

About production technology

As the name implies, cast products are made by pouring molten metal into special molds (casting method). The sequence of technological operations looks like this:

1. Metals - the ingredients are placed in a furnace, melted and mixed.
2. The alloy is fed to the mold and poured into it with a special ladle.
3. After hardening, the workpiece is removed from the mold and moved to machining. At the same time, the structure of the rim and spokes is already formed, it remains only to remove excess material along the edges and refine the holes for the bolts, as well as balance the disk.
4. The last stage is testing under certain speed and shock loads.

Reference. At factories of well-known brands, the process is carried out in a fully automatic mode using CNC machines, even casting is performed by a robot. Manual labor is practically excluded.

The name "forged" does not quite accurately reflect the method of production of these discs, since they are not forged, but squeezed out of a heated alloy on high-power hydraulic presses. The manufacturing algorithm is as follows:

1. As in the previous case, an alloy is prepared in the furnace, from which cylindrical blanks are cast.
2. Each blank goes through several pressing operations, where it is formed into a solid wheel rim without spokes and holes.
3. Products undergo 2 heat treatment operations - hardening (strengthens the alloy) and tempering to relieve internal stresses in the metal.
4. With the help of machining on various machines, holes are made in the disks, the spoke pattern is cut out, excess material is removed along the edges and balancing is carried out.
5. Testing is carried out on special equipment under critical loads.

Note. So the second myth has been dispelled - that due to the manufacturing technology, forged wheels cannot boast of a diverse design. On CNC milling machines, any, even the most complex pattern, can be cut into the body of the workpiece.

Pros and cons of cast products

The main advantage of cast alloy wheels is their attractive appearance, which makes a car of any age and brand look much nicer. And the choice of products in terms of configuration and number of spokes is incredibly wide. This is the main reason that encourages car enthusiasts to change steel wheel rims to light alloy ones.

Other advantages also matter, but they are technical in nature:

• reduced mass of products gives less fuel consumption and increases the controllability of the car;
• for the same reason, the acceleration dynamics of the car improves, and the braking distance is reduced;
• products are initially balanced due to production technology;
• long service life.

Of the listed positive points, only the durability and balance of alloy wheels are really noticeable when the car owner changes tires in a tire shop. Improvement in handling and acceleration dynamics can only be felt by an experienced driver, and the change in fuel consumption is so insignificant that it is not noticeable at all (0.1-0.2 liters per 100 kilometers). Therefore, the beauty of alloy wheels remains a priority, and only then their technical parameters are valued.

Now for the disadvantages:

1. Products are afraid of strong and sharp blows. A crack appears in the thinnest place or where an air shell has formed inside the metal. Manufacturers claim that the casting cannot be repaired.
2. The price of the product is higher than that of stamped steel discs. Due to the difference in prices, the difference can be from 50 to 200%.
3. Cast rims should not be used on vans and light trucks as they are not designed for such loads.
4. Maintenance operations for such products at a tire fitting (tire change, balancing) are more expensive.

Reference. In the countries of the post-Soviet space, there are many workshops where specialists have got used to soldering cracks in aluminum castings. But such a repair cannot be called complete, and restored disks must not be placed on the front axle of the car.

Advantages and disadvantages of forged wheels

The essential and only drawback of forged rims is the high cost, exceeding casting by 2-5 times, depending on the manufacturer. But for this money you will receive such advantages:

• reliability and durability;
• durability, the pressed rim will last as long as the car itself;
• low weight of the product (even compared to casting), which improves the behavior of the car on the road and reduces fuel consumption.

Thanks to pressing and hardening in the manufacture of such rims, the metal does not have hidden shells and acquires increased strength, so impact cracks are extremely rare. In addition, the spokes of the product can be made thinner and more openwork, giving the wheel design additional lightness and beauty. That's what you pay money for when you buy a forged wheel.

Stamped steel rims - the secret of popularity

More than 60% of all cars in the territory of the post-Soviet countries are equipped with disks made of carbon steel sheet. The vast majority of these machines are equipped with such wheels from the factory, since they are cheaper than others. Exceptions are cars in the “luxury” configuration or elite brands for which “stamping” frankly does not fit in appearance.

Despite the low cost, iron discs have many advantages:

• compared to aluminum alloy, steel has ductility and elasticity, so the rim partially absorbs shocks when driving over large irregularities;
• for the same reason, steel products are easy to repair - deformed places can be straightened, and cracks can be welded;
• scope - transport of any purpose and carrying capacity;
• low prices for wheel maintenance;
• there are no problems with fastening the wheels, for which factory (regular) bolts are used.

The most valuable advantage when driving on our roads is the high repairability of stamped discs and the ability to absorb shocks. Combined with low cost, these features make traditional iron rims the most attractive in the eyes of ordinary users. To understand how their cost is formed, it does not hurt to get acquainted with the manufacturing technology of such products.

Production by stamping

For the manufacture of iron rims, thick sheet steel is used. Workpieces of two types are cut from it - a circle and a strip, sent for further processing. The process looks like this:

1. On a hydraulic press, the core of the future disk with bolt holes and technological openings is stamped from a steel circle.
2. The strip is sent to the rollers, where it is bent into the shape of a cylinder. The ends of the sheet are welded together, after which the seam is cleaned.
3. A hydraulic press squeezes the finished rim out of the cylinder, then a hole for the valve is drilled in it.
4. Both elements are connected by welding, then covered with primer and painted.

In the manufacture of stamped products, expensive CNC machines and furnaces are not used, which is why energy costs are significantly lower. Hence the low price of the final product.

Weaknesses of steel wheels

Compared to attractive lightweight aluminum alloy products, forged iron rims lose in appearance, which is often the reason for replacing them. Plastic decorative caps, which are always lost on the potholes of our roads, do not solve the issue, and the owner of the car has to buy new ones.

For reference. To prevent the caps from flying off the wheels, many drivers fasten them to the disks with plastic wiring clamps. This helps, although it somewhat spoils the appearance of the car.

There are other negative aspects in the operation of "stampings":

• due to the large weight of the wheels, the controllability of the machine is worse, and fuel consumption is higher;
• increased stopping distance;
• stamped iron products cannot boast of good balance;
• metal rusts, and therefore requires care.

Judging by the statistics, the listed shortcomings do not bother most Russian drivers too much. Again, some of the negative points are misinterpreted by sellers. For example, the assertion that steel can rot in 2 years and the disk will become unsuitable for further use is unfounded. To bring the metal to such a state, it will take a period twice as long, and with timely care, the product will last no less than light alloy.

Note. There is a myth that the paint of stamped rims is easily scratched and quickly deteriorates, and the light alloy surface cannot be damaged. The second part of the statement is incorrect, alloy wheels can also be scratched, but it is much more difficult to paint them.

The choice of the type of rims is best done according to three criteria:

• depending on the operating conditions of the machine;
• class and brand of car;
• active driving in the cold or warm season.

Advice. If you expect to use one set of rims year-round, then taking into account Russian road conditions, it is better not to risk money and put a steel "stamping".

The ideal option is to have 2 sets of discs, using them in the warm and cold seasons. For summer driving on asphalt surfaces, light-alloy rims are perfect, but for the winter you need to put stamped ones. The problem is ice that appears on the pavement due to unremoved snow, which is why a flat road is covered with continuous potholes. The same frost along the edges of the roadway will easily scratch your beautiful titanium wheels when you drive to the side of the road or come close to the curb.

When choosing a set of new disks, it does not hurt to take into account other recommendations:

1. It is not worth shelling out and buying light alloy products if you are driving through the fields in an SUV. And vice versa, elite cars operated on flat roads should not be stamped, it looks reprehensible.
2. Forged wheels are suitable for any passenger car and various driving conditions, except for frank off-road.
3. Don't try to put light alloy rims on a minibus that's in commercial service, you risk ruining them quickly.

When choosing forged products, a natural question arises - how to distinguish them from casting with external similarity. After all, an unscrupulous seller can slip you a cheaper product at the price of forged wheels. There are some tips for this:

1. Forging is easier than casting. For example, a 15-inch forged rim weighs no more than 5 kg, and a cast rim weighs 7-8 kg.
2. On pressed products processed by milling machines, you will not find burrs or small flash along the edges, as is the case with casting.
3. As a rule, inscriptions on alloy wheels protrude above the surface, and on forging they are deepened, because they are applied by extrusion.
4. If the product is branded and is accompanied by documents, then in the forged rim specification you will find the corresponding English word - FORGED.

Advice. There are many exceptions to these rules that appear when studying the products of domestic or Chinese manufacturers. The best option is to buy forged car wheels in outlets with an impeccable reputation or from authorized dealers.

Despite the numerous advantages of light alloy wheels, they cannot win even half of the Russian market. A similar situation is observed in the countries of the former USSR, where stamped products are more relevant and more practical than aluminum ones. A change in trend should not be expected until there is a dramatic improvement in paved roads.

If your car has cast alloy wheels, you will probably be interested to know how and from what they are made. The manufacturing technology of alloy wheels is much more complicated than it might seem at first glance. Everything matters: alloy choice, temperature, machining methods and more./p

Car rims start with metal

Reading reviews about alloy wheels, you probably noticed that the products of some brands are admired, while others are a surge of negativity. The quality of the basis of future wheels largely depends on the composition of the alloy. Most brands produce alloy wheels from durable aluminum alloys with the addition of other metals. For inexpensive models, an alloy with an addition of silicon is usually used, for example, g-AlSi10/11 or g-AlSi7. They tolerate heat treatment well, show relatively good resistance to mechanical stress. For higher-quality wheels, the composition of the alloy is somewhat different: aluminum is still the basis, and magnesium or titanium act as additives.

How it's done? At the initial stage, metals in the form of blanks are sent to the furnace, where they are heated to a melting point of 600-700 degrees Celsius. The molten alloy is then poured into a mold. However, not everything is so simple, because manufacturers use different technologies.

Casting methods

To obtain a casting, the plant can use different casting methods:

• gravitational (in a chill mold);
• with backpressure.

The choice of method depends both on the alloy and on the estimated cost of the discs (for the budget category, less expensive options are often used). Each method has its own set of advantages and disadvantages. If gravity casting is used, the machines are poured into molds of aluminum alloy at normal atmospheric pressure. After cooling, a workpiece with a uniform fine-grained structure is obtained. For magnesium discs, they try to use other methods, since the metal has to be heated to higher temperatures, and the quality is not very high during the cooling process.

When casting under low pressure, as the name implies, it is necessary to create a rarefied atmosphere. This requires additional costs, but pays off: less metal is required, and the castings are 10-15 percent stronger and almost twice as ductile, which directly affects the further processing and characteristics of the wheels.

An even more advanced method is counter-pressure casting. This time, gas pressure acts on the workpiece, which leads to compaction of the alloy and a decrease in the amount of rejects. Discs made in this way are 5-10% stronger than those cast under low pressure. In addition, the technology allows to reduce the casting time.

Testing

The next stage, without which it is impossible to do, is quality control. In modern enterprises, it is carried out automatically. Special equipment detects voids and cavities, checks the density of workpieces, determines violations of the specified dimensions. If a defect is found during the inspection process, it is sent for remelting, so that the percentage of waste is quite small.

In some cases, the discs go through a hardening stage in order to acquire greater hardness. Heating and cooling are carried out several times, and the temperature range during hardening is from 150 to 200 degrees. However, this operation can make the alloy brittle, so that it will not bend, but will crack or burst if hit hard.

Finishing

The surface of the workpiece is very different from the finished product, so it is necessary to remove everything unnecessary from the surface. For this, future disks are turned on special machines. The cutters give the blank a shape, after which a second quality control is carried out.

What happens next depends on the chosen design. Some models are polished, others are mattified by chemical or mechanical processing. Some brands that produce multi-colored bright wheels for tuning include one more operation in the process: painting. At modern enterprises, polymer powder paints are usually used, which form a durable and uniform coating on knitting needles or a decorative cap. Then comes the turn of the last check, after which the rims go to the warehouse of finished products, and later they are sent to official dealers who distribute them to stores.

In the article we will talk about how to choose the right alloy wheels, what parameters you should pay attention to and what nuances there are when choosing and installing.

The content of the article:

First of all, when tuning a car, motorists immediately try to install new wheels, replacing regular wheels with alloy wheels. To date, there are many configurations and types of alloy wheels. Young motorists often put disks of this type on domestic cars, and this is true, they immediately change their appearance for the better. But the replacement process is not always so easy. It is necessary to select the size of the wheel arches, so that later it does not rub on the fender liner, the parameter that is responsible for this is considered to be the diameter.

What are cast

The material from which the discs are made is considered important. Now they are made of titanium alloy (very rarely), aluminum or magnesium alloys. Aluminum alloy wheels are among the best. Most often they can be found in expensive car dealerships. They are less susceptible to corrosion and look more attractive.

Each owner individually selects the design and color, here you can argue ad infinitum. You can pick up both in the market and in a specialized auto shop they will show you how your car will look with themes or other disks.

Disc material

Design is not the main thing when choosing, but what the element is made of has a role. According to the composition of the material they recognize:

1. Cast magnesium - light, but very capricious to blows and quickly crack;
2. Cast aluminum - the most optimal in terms of the combination of qualities;
3. Forged aluminum - durable and lightweight;
4. Forged magnesium - super strong and lightweight.

I want to say right away that you should not take magnesium ones - both cast and forged ones cost a lot of money, they are often made to order and only for sports cars. The price can start from $ 1000 per piece. Therefore, it is better to take the optimal ratio of the price of cast and the price of a car, since buying a car for $5,000 and investing another $4,000 in wheels makes no sense, and the quality will not increase for the better.

Diameter (R)

Regarding the diameter of the cast ones, you should choose the best option, it is often advised to take the same diameter as the native disks, because of this it will not rub the tire on the fender liner, it will not tear the wings when cornering, and it will not occur when the axle is loaded problems. It is customary to measure it not in centimeters, but in inches. It is allowed to take a slightly larger diameter, but then you have to take a smaller tire diameter. But given our roads, low-profile tires are not the best option, ruin the wheels faster. If an ordinary disk can be brewed, then cast ones, unfortunately, even brewing for a long time is not enough. For a couple of thousand kilometers, or until the first good hit. It will be possible to brew only with argon welding. The maximum that can be done is to roll the disk during deformation.

Departure (ET45)

In addition to the diameter, you should pay attention to the offset (ET45 - standard), the so-called distance between the plane of the disc and the plane of the disc mounting itself. For each disk, this parameter is different and can be measured from millimeters to centimeters, often referred to as OFFSET. It is worth following the recommendations for selecting this parameter. Some violate this parameter and put wider discs, this increases stability and maneuverability. But where there are pluses, there is also a minus, this will entail an increase in the load on the hub bearings, an increase, since the load on the motor will increase.

Next on the list is the PCD parameter or, in other words, the diameter of the centers of the mounting holes and their number. The store will recommend you what size will fit your car. Sometimes motorists still buy unsuitable wheels and then completely change the hub, or put special stands, this will allow you to adjust the parameters of the car to the wheels.

When installing discs, make sure that the mounting bolts are of the right size, they should not be too short or too long. If they are too short, they will be cut off at the hub. If too long, they can press and damage the brake disc or other moving parts of the wheel.

Some manufacturers indicate the DIA parameter, the diameter of the central hole of the disk (measured from the side of the mating plane, measured in mm), often they try to choose the optimal size bolts for this parameter. If the hub has not been changed, then the auto shop will immediately tell you which bolts are better to take.

Now an example of decoding the inscriptions (technical characteristics) of all disks. Let's take an example: J5.5x14, 4x100, ET49, DIA56.6 - this means a 5.5" wide wheel with a R14" radius, with four mounting holes on a circle with a radius of 100 mm, with an offset of 49 mm and a hub hole diameter of 56.6 mm.

It is not worth replacing alloy wheels at home in the grandfather's way, as you will immediately leave traces and damage on the discs. The first thing to do after purchase is to install and try on an alloy wheel without a tire on the hub of your car. We remove the native wheel, and install a new disk, if all the parameters are observed, then it should become like a native one the first time. After installation, move it around, it should not move, there should not be any backlash. Now we put the native wheel again and go to the service station to change the car.

At first, you should not immediately step on the gas and test new wheels, let them get used, and at the same time see how the car behaves with new wheels.

When buying, many are wondering how not to fall for a fake. I will say that only experienced specialists can determine the quality by eye, and no one in the store will allow you to test it. Usually sellers will persuade you to buy exactly what they consider the best (this is not always the case), they should not be trusted, as they are not always honest and objective. It is better to buy discs in specialized salons with a guarantee, often such salons value their reputation and will not slip low-quality goods. Do not hesitate to demand documents for discs and a certificate of quality from the manufacturer.

Popular brands include Asanti, Lexani, Fuel, Vellano, Rucci. Prices for discs can vary from $50 to $5000-6000. For example, such an alloy wheel LEXANI FORGED 105, the cost of which starts from $ 1000, expensive sports cars are often equipped with such wheels.
