The magnesium alloy automotive wheel project of Dewei Corporation adopts international advanced patented technology, complies with the national research and development requirements of energy saving and emission reduction for lightweight automobiles, reduces the quality of automobiles to reduce fuel consumption and pollution, and improves safety performance. With a total investment of 500 million yuan, the company has built a production line in the first phase with an annual output of 350,000 magnesium alloy automotive wheels. It was officially put into production in August 2017, and by the end of 2018, all three production lines were put into production, realizing the goal of annual output of 1 million magnesium alloy automotive wheels.
Characteristics of magnesium alloy automotive wheel hub
1. Safety, magnesium alloy automotive wheels have high strength, good impact resistance and fatigue resistance; Light mass, reduce the inertia energy, reduce the torque required for driving, fast speed, fast braking; Low temperature dependence, good heat dissipation performance, prolong the service life of tires.
2. Comfortable. Magnesium alloy material has good damping, strong shock absorption, shock absorption and noise reduction, which improves the comfort of the car.
3. Operability. The mass of magnesium alloy automobile wheels is 1/3 less than that of aluminum alloy automobile wheels, which means that the suspension system has better dynamic response ability, thus making the operation more superior.
4. Energy-saving, magnesium alloy automobile wheel weight is light, reduce the load of the whole vehicle (the wheel is unsprung mass, the weight reduction effect is 15 times of the body weight reduction), thus reducing energy consumption, fuel saving, fuel saving rate of 8%-18%.
