Any owner of a car at least oncethought about which discs would be optimal for his "iron horse". Of course, cast models will provide the car with a vivid memory. However, experts say that stamped discs have their advantages, and the choice should be based on personal feelings. Let's conduct a small comparative analysis of "casting" and "punching". Perhaps this will help to form their own opinion on this issue.
Methods of manufacture and materials
Cast wheels are called because of their waymanufacturing. The molten metal is poured into the prepared form. As the material used alloys, the basis of which is aluminum or magnesium. Stamped disks are assembled from two elements. They are connected by spot welding. The material that is used is sheet steel. Stamped disks have a lower cost than cast ones. The composition of the material from which they are made determines their basic distinctive properties.
Characteristic differences of cast discs
As already mentioned, for many motoristsThe decisive factor when buying cast discs is an attractive appearance. This is not their only advantage. Used in the manufacture of metals can reduce the total weight of the product. This gives a small fuel economy when driving. In addition, the lightweight wheel quickly returns to its original position after contact with the roughness of the road surface. This improves the handling of the car. However, it is very difficult to notice such improvements and can be done only by a professional driver. There are cast wheels and flaws. They have a more brittle structure than the pressed discs. Steel from impact is deformed, and a cast disk can crack or form a chip. Hidden cracks pose a danger to the driver and passengers. Such a cast disk can simply split when it hits a road hole and provokes an accident. You can restore the cast wheel. Such services are provided in some repair shops. However, if the hardness of the disk is damaged, the product can not be repaired.
What is characteristic of stamped disks?
It is these wheels that car manufacturersmost often set for their products. Although they do not belong to the pride of designer artists, many consider them to be quite practical. The most common in Russia since the times of the Soviet automotive industry are stamped disks R13. However, some motorists are confident that a larger radius increases the handling and patency of the car. Therefore, they try to maximize the size of the wheels. Stamped R14 wheels on the WHA help in this case to find a perfect way out. Speaking about the advantages of steel wheels, it is necessary to note their high maintainability. Dents on the disk are easy to straighten. In addition, the rim of the disc is able to partially extinguish the force from a strong impact, which can not be done by a rigid cast construction. This positively affects the condition of the running gear of the car. The negative aspects include the fact that stamped discs are prone to corrosion and require careful care.
