The alloy is applied to automobiles, which not only has obvious energy-saving effect, but also meets the development trend of safety, environmental protection and automobile materials, and has significant economic and social benefits. Since the weight of the car body is very important in the whole vehicle, the development of high-performance and distinctive automobile body panels is an important part of the lightweight process of automobiles in China.

At present, there is no large-scale application of aluminum alloy in the body panels of automobiles in China, mainly because the price of aluminum alloy is about 2 times higher than that of ordinary steel, and the stamping forming of aluminum alloy steel sheets is more difficult than ordinary steel sheets. These two problems plague the use of aluminum alloy sheets for automotive body applications. But with the continuous development of science and technology, these problems will be well resolved.

First of all, the improvement and progress of smelting technology will increase the productivity, so the unit price of aluminum alloy will continue to decline and the environmental protection concepts of governments and people around the world will gradually increase. Therefore, it is strongly required that automobile manufacturers adopt more by changing technology and cost. More aluminum alloy.

Secondly, the problem of low stamping performance of aluminum alloy sheet can be achieved by rationally optimizing the proportion of each alloying element by material research, and improving the overall performance of the alloy by reasonable ratio and interaction between elements. On the one hand, it is possible to improve processes such as heat treatment processes and rolling processes to improve the stamping forming ability of aluminum alloy sheets.
