1, steel wheel hub
Steel wheels, which are made of steel, are also a more common material. The advantages of steel wheels are low cost and low cost, but a penny a penny, its heat dissipation ability is very poor, and it is easy to rust in rainy days.
2, aluminum alloy wheels
The main material of aluminum alloy wheel is aluminum, and it is made of metal materials such as manganese and magnesium. Compared with steel wheels, it is relatively light, so the car with aluminum wheels will be more fuel-efficient.
3. Magnesium alloy wheels
The main material of magnesium alloy wheel is magnesium, and other metal materials are added. This material is the lightest, so it is now loved by the owner, its shock absorption performance is better, but also easy to heat, corrosion resistance.
4, carbon fiber composite wheel hub
Carbon fiber composite wheel is made of a composite material, so its cost is relatively high. But on the other hand, its anti-noise performance is better, even if damaged, it is easy to repair.
