1. Steel wheels
The main advantage of the steel wheel hub is that the manufacturing process is simple (the casting process is generally used), the cost is relatively low, and the resistance to metal fatigue is strong. However, the disadvantages of steel wheels are relatively prominent: ugly appearance, large weight, large inertial resistance, poor heat dissipation, and very easy to rust.

2. Aluminum alloy wheels
Aluminum alloy wheels are mostly made of aluminum as the basic material, with appropriate addition of manganese, magnesium, chromium, titanium and other metal elements. Compared with iron hubs, the mass is small. Aluminum alloy rims should be light and small steel rims, which can make a great contribution to the fuel economy of the vehicle. Moreover, the heat dissipation performance is good, which can improve the tire life. Some aluminum alloy rims can rely on their own styling functions to direct the airflow to the brakes during rotation to improve heat dissipation.

3. Magnesium alloy wheels
Magnesium alloy is an alloy composed of magnesium as the base and other elements added. Its characteristics are: low density (about 1.8g/cm3 magnesium alloy), high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, and impact resistance The load capacity is larger than that of aluminum alloy.
