The main benefit of steel wheels is the simplicity of the manufacturing process (casting processes are generally used, for example, aluminum alloy wheels are usually produced by low-pressure casting processes). The cost is relatively low, and the ability to resist metal fatigue is very strong, which is what we commonly call cheap and Strong. However, the defects of steel wheels are relatively prominent. They are ugly in appearance (it can be said that there is no appearance at all), large in weight (the same wheel steel material is much heavier than aluminum alloy material), inertial resistance is large, and heat dissipation is relatively poor. And it is very rusty.
Alloy material wheels can just compensate for such problems. They have lighter weight, low inertial resistance, high manufacturing accuracy, small deformation during high-speed rollover, and low inertial resistance, which is conducive to the straight-line travel function of traveling cars and reduces tire roll resistance. Reduced fuel consumption. The heat conduction function of the alloy material is about three times that of steel, and the heat dissipation is good. Regarding the braking system of the vehicle, the thermal attenuation of the tire and the braking system can play a certain role. The alloy wheels of the original cars on the market are mainly made of aluminum alloy. Of course, many modified wheels will choose chromium, titanium and other elements as the base material in order to meet certain special requirements and visual progress. However, compared with steel wheels, the price of alloy wheels is much more expensive. Therefore, in many low-end and middle-end OEM cars, steel wheels will appear on low-profile models, while alloy wheels are high-profile. Standard equipment of the model.
