What Are Alloys of Autobody Aluminum Sheets

Aluminum alloy has good corrosion resistance, and also has excellent properties of light weight, high strength, high specific stiffness, and can be welded. As the representative of today's lightweight metals and the most modern metal material, aluminum alloy is widely used in automobile manufacturing.

In new energy vehicles, the body accounts for a large proportion of the vehicle's own weight. The application of autobody aluminium sheet in the body can reduce the weight of the vehicle while increasing the cruising range. In addition, with the increase in the aluminumization rate of the body of new energy vehicles, it is necessary to increase the research on the body application in aluminum alloy forming technology, maintenance, etc., to reduce the manufacturing cost of aluminum alloy body, so that aluminum alloy body can also be popularized in low-end new energy vehicles.

Aluminum alloys are widely used in the body structure of automobiles, including body frames, doors, roofs and other parts. Due to the lightweight characteristics of aluminum, the use of aluminum alloys can reduce the overall weight of the car and improve fuel efficiency and performance.

5 series aluminum, that is, aluminum-magnesium alloy, is usually used for car interior covering parts, such as doors, roofs, floors and other parts. This type of alloy has good formability and corrosion resistance, and is suitable for decorative and structural parts inside the car body. Since 5 series aluminum has moderate strength, it is usually not used for external covering parts that withstand greater impact.

Al 5754 belongs to the Almg3 series, and its magnesium alloy content is higher than that of 5052 aluminum sheet. 5754 aluminum sheet belongs to medium-strength aluminum alloy sheet, and its magnesium alloy content is between 2.6-3.6. It has good anti-rust and corrosion resistance, no color difference on the anodized surface, excellent processing performance, excellent corrosion resistance, high fatigue strength, high weldability and medium static strength.

Aluminum alloys for car doors should have high fatigue resistance, excellent corrosion resistance and excellent processing performance. 5754 aluminum plates for car doors can make passengers more comfortable, the doors are easy to close, the door locks are safe and reliable, and the noise is low. In addition, aluminum alloys can be recycled, which makes its environmental performance more prominent.
