The 5xxx Aluminum Alloys for Car Door Shell

With the urgent need for environmental protection and energy saving, fuel vehicles need to reduce fuel consumption, reduce exhaust gas, and improve efficiency. Replacing steel with aluminum alloys is one of the main weight reduction methods adopted by major automobile manufacturers. 5xxx aluminum alloy is usually used for body inner panels for it has good corrosion resistance and welding performance.

For parts such as car door shell, car hoods, and car front and rear fenders, the mature products we have developed are 5182 aluminum alloy. 5182 aluminum plate has good stamping effect. After the aluminum plate is punched, there is no cracking phenomenon. Haomei Aluminui mcan offer 5182 aluminum sheet of 0.15-600 mm and the width range is 20-2600 mm.

5754 aluminum sheet is widely used in the automotive lightweight industry. It has good formability, excellent corrosion resistance, weldability and easy processing. 5754 aluminum alloy sheet with different tempers is the main aluminum alloy used in the automobile manufacturing industry (car doors, molds, seals) and the canning industry.

5052 grade aluminum cannot be strengthened by heat treatment. It is suitable for parts with complex shapes such as the inner panel of the car body. 5052 aluminum plate has high strength, high resistance to stress corrosion cracking, and small tendency of weld cracks, which can ensure the safety performance of automobiles.

In addition, the 5052 aluminum plate can effectively reduce the weight of the body and reduce the fuel consumption, so as to realize the transformation of automobiles from "high energy consumption" to "low energy consumption and low emission".
