The wheels can be divided into two categories according to the material: steel wheels, alloy wheels.
At present the original wheel on the market in accordance with the material can be divided into steel wheels and alloy wheels, both of which have advantages and disadvantages.
The main advantage of steel wheels is the simple manufacturing process, the cost is relatively low, and the ability to resist metal fatigue is very strong, that is, we commonly known as cheap and strong. But the shortcomings of the steel wheel is also relatively prominent is the appearance of ugly (it can be said that no appearance at all), the weight of the larger (the same wheel steel material than aluminum alloy material is much heavier), inertia resistance, heat dissipation is also relatively poor, And very easy to rust.
In contrast, the alloy material hub can just make up for such problems, lighter weight, inertia resistance is small, the production of high precision, high-speed rotation when the deformation is small, inertia resistance is small, is conducive to improving the car's straight line performance, Tire rolling resistance, thereby reducing fuel consumption. Alloy material thermal conductivity is about three times the steel, good heat dissipation, for the vehicle's braking system, tire and brake system thermal attenuation can play a role. Currently on the market of the original car alloy wheels have been aluminum-based, of course, many modified wheels in order to achieve certain special requirements and visual improvement will choose chromium, titanium and other elements as a basic material. However, compared with the steel wheel hub, the price of alloy wheels to a lot of expensive, so often in many low-end level of the original car, the steel wheels will appear in the low with models, while the alloy wheels are high with Models of the standard.
1 steel wheel The main advantage is the simple manufacturing process, the cost is relatively low, strong resistance to metal fatigue. But the shortcomings are also obvious, such as heavy, inertia resistance, poor heat dissipation and so on.
2 alloy wheels its advantages are light weight, high manufacturing precision, strength, inertia resistance, heat dissipation, visual effects and so on, the disadvantage is the manufacturing process is complex and costly.
Alloy wheels and more aluminum as the basic material, the appropriate addition of manganese, magnesium, chromium, titanium and other metal elements. Compared with steel wheels, alloy wheels with energy saving, safety, comfort and other characteristics, so more and more cars have the alloy wheels as a standard configuration. Here we look at the three characteristics of alloy wheels.
1 energy-saving alloy wheels of light weight, high manufacturing accuracy, high-speed rotation in the small deformation, inertia resistance is small, is conducive to improving the car's straight line performance, reduce tire rolling resistance, thereby reducing fuel consumption.
2 safety aluminum thermal conductivity is three times the steel, cooling effect is very good, thereby enhancing the braking performance, improve the tire and brake disc life, effectively protect the car's safe driving.
3 comfortable alloy wheels with the general use of the buffer and shock absorption performance is better than ordinary tires flat tires, so that the car on the uneven road or high-speed driving, the comfort greatly improved.
