The aluminum alloy plates currently used for automobile bodies mainly include 5000 series and 6000 series. 5000 series alloy is an aluminum alloy that cannot be heat treated and strengthened. It has moderate yield strength and tensile strength, corrosion resistance, processability and good weldability.
5052 aluminum sheet has the features of high formability and high surface treatment effect, and is widely used in vehicle interior panels. It is also used for the manufacture of fuel tank panels. The body side panels and inner panels of semi-trailers are 5052 aluminum plate with a thickness of 4-5mm. 5052 h32 aluminum sheet is a common choice.
The bus body skin is a thin aluminum plate covering the outer surface of the bus body frame. The use of the skin material affects the surface quality of the bus body. With the requirements of environmental protection and energy saving, bus skins have also started to be lightweight. The body skins generally use 5052 aluminum plates.
In the space frame, 5052, 5182 and 5059 aluminum plates from Haomei Aluminum generally meet the requirements due to excellent corrosion resistance and good processing performance. Extruded profiles mainly use 6005, 6063, 7003, 7075 alloy hollow aluminum profiles. The key issues are thin thickness, appropriate strength, easy combination with other materials, and reasonable design of the joint cross-section shape.
1. Lightweight design
5052 aluminum yield strength is high. It is of light weight and high strength. The alloy's high specific strength means it can reduce component weight while maintaining strength, thereby reducing material costs.
2. Corrosion resistance
5052 aluminum plate contains magnesium, which has good corrosion resistance and can resist the erosion of humidity, chemicals and other environmental factors. This gives 5052 aluminum panels excellent durability in outdoor and harsh environments.
3. Easy to process
5052 aluminum sheets are easy to cut, bend and weld, making it easy for car manufacturers to fabricate parts to different specifications and requirements. The material's ease of processing aids productivity and reduces manufacturing costs.
4. Recyclability
5052 aluminum is a recyclable material that helps reduce environmental impact. With increasing environmental awareness, choosing recyclable materials can help reduce resource waste and waste emissions.
