The advantages of aluminum sheet metal in automotive industry

2018-06-01

The application of aluminum sheet metal in automobiles has not only obvious effects of energy saving and weight reduction, but also meets the development trend of safety and environmental protection of automotive, and has significant economic and social benefits. As the weight of the car body plays a decisive role in the vehicle, the development of high-performance and distinctive automotive body panels is an important part of the automotive lightweight process.

There is no large-scale application of aluminum sheet alloys in auto body panels. The reason is that the price aluminum sheet price is about twice higher than that of ordinary steel and the aluminum alloy sheet is more difficult to punch and form than ordinary steel. These two problems plagued the use of aluminum 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 sheet 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 buy using aluminum alloys.
Secondly, for the problem of low stamping performance of aluminum sheet metal, 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 ratios 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 stamping ability of aluminum alloy sheet.
