With the demand for environmental protection and energy saving, the lightweight of automobiles has become the development of the global automobile industry. Aluminum as a representative material of automobile lightweight, has become a key raw material for reducing the weight of automobile bodies. Aluminum alloy sheet has the advantages of light weight, high strength, good stretchability, corrosion resistance, etc. The formability and production performance of aluminum sheet are very close to those of steel sheet, so it is very popular in the automobile and auto parts processing industry. Aluminum alloys can also be applied in body, frame, engine, door, cover, fuel tank and compartment body according to the different alloys added, different proportions and different manufacturing processes, which can effectively reduce the overall weight of the vehicle, thereby improving the comprehensive performance.
Commonly used alloys for automotive aluminum sheets are 5*** series and 6*** series. The main aluminum sheets plates for automobiles are:
5182 aluminum sheets plates, 5083 aluminum sheets plates,
5086 aluminum sheets plates, 5754 aluminum sheets plates,
5052 aluminum sheets plates, 5454 aluminum sheets plates,
