In order to reduce fuel consumption, automobile manufacturers use lightweight materials to manufacture car bodies. Aluminum alloy materials have excellent performance and cost-effectiveness, and have become the mainstream materials for lightweight automobiles. The car’s opening and closing modules are mainly the four doors, the front hood and the trunk lid. They are an important part of the car’s lightweight. 5083/5182 aluminum plate is an aluminum alloy commonly used in the automotive industry, including car trunk lid applications.
5083 aluminum plate for car trunk lid: 5083 aluminum alloy is a kind of rust-proof aluminum with high strength, especially fatigue resistance, high plasticity and corrosion resistance, and cannot be strengthened by heat treatment; the plasticity is still good when semi-cold work hardening, and the cold when hardened, it has low plasticity, good corrosion resistance, good weldability, poor machinability, and can be polished. 5083 aluminum plate is mainly used in applications that require high plasticity and good weldability, such as welding parts of ships, vehicles, automobiles, and aircraft panels. It is a commonly used light automotive aluminum plate.
5182 aluminum plate for car trunk lid: Like 5083 aluminum plate, it belongs to the Al-Mg series alloy and has good corrosion resistance, excellent weldability, good cold workability, and medium strength. However, the tensile strength and yield strength of 5182 aluminum plate are slightly better than 5083 aluminum alloy. Due to the addition of a small amount of Si, the welding performance of 5182 aluminum plate is very good and can be used for gas welding, argon arc welding, spot welding and seam welding. 5182 aluminum plate is easy to paint and coat, which is very important to achieve the desired appearance and beauty of the trunk lid.
