Lightweight automobile has become an industry trend. 5754 automobile aluminum plate is based on Al-Mg alloy, giving consideration to lightweight, corrosion resistance and formability, which meets the manufacturing requirements of core parts of automobile body.

5754 aluminum plate belongs to Al-Mg rust-proof aluminum alloy, with magnesium content of 2.6%-3.6%, and optimized proportion of trace chromium and titanium, with a density of about 2.7g/cm³. Compared with traditional steel, the aluminum plate has obvious weight loss, which helps the whole vehicle to reduce energy consumption and improve battery life, and is in line with the direction of lightweight body material selection. Its tensile strength is 165-265MPa, which belongs to medium strength, giving consideration to structural rigidity and impact resistance, and is suitable for use in doors, body shells, oil tanks and other parts.


The corrosion resistance is outstanding, and the dense oxide film cooperates with alloy components, which can resist environmental erosion such as humidity, salt spray and snow melting agent, reduce the corrosion of car body parts, prolong the service life and reduce the maintenance cost. When welding, the crack tendency is low, and the weld strength is close to the matrix, which ensures the sealing and structural stability of the joint of oil tank and car body.

The formability adapts to the automobile stamping process, and the O-shaped plate has good ductility, and can complete complex cold working such as deep drawing, stretching and bending. After forming, the surface is flat without cracks and wrinkles, which meets the requirements of complex body modeling and mass production. The surface quality is stable, and it is suitable for post-treatment such as spraying and anodizing, which simplifies the processing flow of automobile enterprises.

5754 aluminum plate for automobile has complete thickness and width specifications, and can provide O, H111, H32 and other states. It strictly follows the aluminum standards for automobile, adapts to the lightweight scheme of fuel vehicles and new energy vehicles, and provides stable substrate selection for automobile enterprises.
