Generally small cars commonly use aluminum alloy wheels. Because aluminum alloy wheels and steel wheels compared to the wheel, has more energy saving, comfort, safety and other characteristics.
The most important features of steel wheels are simple manufacturing process, relatively low cost, and strong resistance to metal fatigue.
Magnesium alloy wheel elasticity, heat dissipation, shock absorption performance is good, the ability to withstand impact loads than aluminum alloy is also greater, corrosion resistance is also better.
Carbon fiber composite wheel hubs have special vibration damping characteristics, can damp vibration and reduce noise, good fatigue resistance, easy to repair after damage.
