Automotive aluminum advantages and characteristics

[China Aluminum Industry Network] Alloy is applied to automobiles, which not only has obvious effect of reducing energy consumption, but also accords with the development trend of safety, environmental protection and automotive materials, and has significant economic and social benefits. As the body weight of a car plays a decisive role in a vehicle, developing an automotive body plate with high performance and characteristics is an important part of the process of lightweighting in China.

At present, there is no large-scale application of aluminum alloy in auto body panels in China. The reason is that the price of aluminum alloy is about 2 times higher than that of ordinary steel and aluminum alloy steel sheet is more difficult to punch and form than ordinary steel. These two problems plagued the use of aluminum alloy sheet for automotive body applications. However, with the continuous development of science and technology, these problems will be well resolved.

First of all, the improvement and progress of smelting technologies will increase productivity, so the unit price of aluminum alloys will continue to decline, and the environmental protection concepts of governments and people around the world will gradually increase, which will strongly require auto manufacturers to adopt more changes in technology and costs. Many aluminum alloys.

Secondly, for the problem of low stamping performance of aluminum alloy sheet, on the one hand, the material ratio can be used to reasonably optimize the proportions of alloying elements in each alloy, and the comprehensive properties of the alloy can be improved by reasonable proportions and interactions between the elements. On the one hand, it can improve the process such as heat treatment process and rolling process to improve the aluminum alloy sheet stamping capacity.
