    There are 2000, 5000 and 6000 Series Aluminum Sheet Plate for automobile body, and the most common ones are 2024, 5052 and 6061. The body is the heaviest part of a car, accounting for about 30% of the car's total weight. Therefore, the aluminum sheet for the 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 for major automakers to improve their competitiveness. At present, the main measure to reduce the weight of automobile body is to replace steel plate with aluminum plate. From the perspective of mechanical properties, aluminum alloy can reduce the weight by about 47% compared with traditional steel plates, and can withstand the same or even greater impact. The application of aluminum plate can achieve the effects of energy saving, environmental protection and high recovery rate.
    The main aluminum alloys used for automobile body aluminum sheets are 2000 series, 5000 series and 6000 series. The following are analyzed separately:
    First, the 2000 series. The main features of the 2000 series aluminum plate are high hardness, good forgeability, high strength, in addition to good welding performance and corrosion resistance.
    Second, the 5000 series. The main features of 5000 Series Aluminum Sheet are low density and high tensile strength. Compared with ordinary steel plates, it has good formability and good corrosion resistance. Widely used in automotive interior panels with complex shapes. But its disadvantage is that it is fragile.
    Third, the 6000 series. The overall performance of the 6000 series aluminum plate for the car body is better. Compared with ordinary steel plates, it has better yield strength and tensile strength, good corrosion resistance and oxidation resistance, and is easy to paint and process.
