Market analysis of lightweight automobile "magnesium" and "aluminum" alloy materials

1. Aluminum alloy die casting

Advantages: lightweight, wear resistance, corrosion resistance, good elasticity, excellent impact resistance, good processing, and 100% recyclability, etc., have gradually become the favorite material of automobile companies. Ford recently demonstrated a lightweight technology verification vehicle based on Fusion/Mondeo developed in cooperation with the U.S. Department of Energy. Due to the use of a large amount of aluminum alloy, the car is 363 kg lighter than the standard Mondeo, reducing weight by about 25%. . Part or all of the bodies of Land Rover Range Rover SUVs, Volkswagen Audi A8, Mercedes-Benz CLA, and General Chevrolet Corvette sports cars are made of aluminum. In terms of new energy vehicles, the Tesla Model S has an all-aluminum body, and most of its front and rear suspension materials are also made of aluminum.

Disadvantages: The load-bearing capacity of aluminum alloy is far from that of steel. Therefore, even for cars with all-aluminum bodies on the market, their chassis generally still use steel materials. Moreover, the preparation process of aluminum alloy is complicated and the cost is relatively high. At present, the models that use aluminum alloys are often mid-to-high-end cars.
