(Summary description)[China Aluminum Industry Network] The wheel hub is one of the most important safety parts on the car. There are steel wheels and aluminum wheels. The wheels are under the pressure of the mass effect of the car and the load. The effect of torque also bears the irregular alternating forces caused by dynamic loads from different directions caused by the car turning, bumpy road, impact of road obstacles during driving.

The quality and reliability of the hub not only affects the safety of the vehicle and the personnel on the vehicle, but also affects the performance of the vehicle during driving, such as smoothness, maneuverability, and comfort. This requires good dynamic balance of the hub and high fatigue strength. With good rigidity and elasticity, high precision in size and shape, and light weight, aluminum wheels meet the above requirements with their good comprehensive performance, and have outstanding performance in terms of safety, comfort, and light weight, and have won the favor of the market. Gradually replacing steel wheels becomes the best choice.

　　 The most important production process flow of automobile aluminum wheels is: melting → refining → material inspection → low-pressure casting → X-ray inspection → heat treatment → mechanical processing → dynamic balance inspection → air tightness inspection → painting.
