Advantages of automotive aluminum:
● Reducing the quality of the entire vehicle is the most effective way to reduce the weight of the vehicle. For every 10% reduction in the weight of the vehicle, the fuel consumption will be reduced by 6% to 8%, and the exhaust emissions will be reduced by 5% to 6%.
● At present, foreign automobile manufacturers such as Jaguar and Audi have adopted all-aluminum bodies. Domestic OEMs are also greatly increasing the use of aluminum alloy products in the body and various accessory systems. The trend of lightweight has become a certainty.
● The lightweight penetration rate of chassis shell parts is currently relatively high, and the lightweight penetration rate of subsequent support products such as subframes, control arms, and steering knuckles will increase.
China's lightweight material technology development route:
