1, light weight, low penetration resistance, high manufacturing accuracy, low time variation at high speed and low penetration resistance, which is beneficial to improve the straight-line driving performance of the automobile and reduce the rolling resistance of the tire, thus reducing fuel consumption.

2. The thermal conductivity of alloy material is about three times that of steel, and it has good heat dissipation, which can play a certain role in the braking system of vehicles and the thermal attenuation of the braking system.

3, the hub is very good, the style and quality of the hub are very diverse, because the style of the hub is very diverse, which can adapt to various complex road conditions and weather environments.
