Analysis of the application of aluminium alloy in automotive lightweighting technology

The progress of social economy and the development of science and technology have led to the continuous improvement of people's living standards, and the use of automobiles has become more and more common, which can provide certain convenience for people's daily travel. However, as the available energy in China has been in a shortage, coupled with the increasing demand for automobiles, it has brought new challenges to the development of the automobile industry. At this stage, in order to meet the strategic objectives of green and environmental protection in China, and to meet people's needs for comfort and light weight as far as possible, the automotive industry must not only continuously improve the overall quality of cars, but also strictly control the production costs of cars, and make reasonable use of new welding technology to effectively improve the situation of air holes and cracks in cars, so that the future development of cars in the direction of light weight The future development of cars will be lighter.

Aluminium has good corrosion resistance, low cost, recyclability, ease of processing and light weight, and its use in the production of cars can effectively reduce energy waste. As far as corrosion resistance is concerned, the surface of aluminium can easily produce the corresponding oxide film, and its strong oxidation resistance can effectively reduce the corrosion degree of the car, and aluminium alloy is especially suitable for the car body where it is not suitable for painting anti-corrosion materials, which can not only enhance the service life of the car, but also improve the aesthetic degree and comfort of the car. In addition, most of the aluminium currently used in China is recycled aluminium, which can effectively reduce the loss of energy, and recycling can effectively reduce energy loss by more than 95%, which is fully in line with the world's conservation and environmental protection requirements. At the same time, the use of aluminium alloys in the production of car bodies can effectively make use of aluminium extrusion technology, thus effectively reducing the number of welding joints, to a certain extent reducing the processing procedures of the car and comprehensively improving the assembly efficiency of car production.
