5083 automotive aluminum shee plate is one of the typical applications of 5083 aluminum alloy. Its material properties are high strength (higher than 5182 aluminum plate), light weight, excellent corrosion resistance, outstanding weldability and good formability. The common states of 5083 automotive aluminum sheet include O state (complete annealing state), H111 (mild work hardening state) and H32 (1/4 hardening state). Its mechanical properties improve evenly with decreasing temperature, and its fracture toughness also improves accordingly. It is a good automotive cover alloy, especially suitable for internal and external welded sheet metal structures such as commercial vehicles, various special vehicles, and semi-trailers.

◆ High strength: 5083 aluminum alloy has the highest strength among non-heat-treated alloys and has excellent mechanical properties.
◆ Excellent corrosion resistance: It has strong corrosion resistance to seawater and industrial chemical environments.
◆ Excellent weldability: The strength of the welded joint is comparable to that of the annealed base material, and still maintains excellent strength.
◆ Lightweight: Low density helps to reduce the weight of the vehicle body and improve fuel efficiency.
◆ Good formability: It has good ductility and formability, suitable for manufacturing parts with complex shapes.
