Aluminium sheet for car bodywork

Aluminium sheet for car bodywork have grade of 2000, 5000 and 6000 series, most common seen are 2024, 5052 and 6061. The car body is the heaviest part of the car, accounting for about 30% of the total weight of the car. Therefore, the aluminum sheet for car body is of great significance to reduce the weight of the car. How to reduce energy consumption and pollution through the application of new technologies is an important measure that major automakers should take to improve their competitiveness. At present, the main measure to reduce the weight of automobile body is to use aluminum sheet instead of steel. From the perspective of mechanical properties, aluminum alloy can reduce the weight by about 47% compared with traditional steel sheet, and can withstand the same or even greater impact. The application of aluminum sheet can achieve the effects of energy saving, environmental protection and high recovery rate.

The main aluminum alloys used in aluminium sheet for car bodywork are 2000 series, 5000 series, and 6000 series. The following are respectively analyzed:

First, the 2000 series. The main characteristics of 2000 series aluminum sheet are high hardness, high forgeability, high strength, in addition, it has good welding performance and good corrosion resistance.

Second, the 5000 series. The main feature of 5000 series aluminium sheet alloy is low density and high tensile strength. Compared with ordinary steel plate, it has good formability and good corrosion resistance. It is widely used in the complex shape of automobile interior panels. But its shortcomings are fragile.

Third, the 6000 series. The overall performance of 6000 series aluminium sheet for car bodywork is relatively good. Compared with ordinary steel plate, its yield strength and tensile strength are better, and its corrosion resistance and oxidation resistance are good, and it is easy to coat and process.
