Aluminum alloy wheel is lighter in weight, less inertia, high precision, low distortion, low inertia, small inertia and small inertia. It is advantageous to improve the car's straight running performance, reduce the tire rolling resistance, thereby reducing fuel consumption. The thermal conductivity of aluminum alloy material is about three times that of steel, good heat dissipation, and can improve the safety and service life of tire and brake system. The company meet market demand, the current development of aluminum wheel forging H661, H631, etc..
