Car body with aluminum alloy material mainly includes 2000 series, 5000 series, 6000 series alloy plates, profiles, tubes and high performance aluminum, different mechanical parts with different types of aluminum alloy material.
Bearing the largest part of the skeleton parts: body, use the 2000 or 7000 series materials, heat treatment reinforcement.
The stress of the secondary parts skin parts: body, use the 5000 or 6000 series materials.
The door part: using 5000 or 6000 series materials.
Bottom part: using 5000 or 6000 series materials.
Interior trim parts: use 1000 or 5000 series materials, heat treatment to strengthen.
Seat parts: use 2000 or 6000 series materials, heat treatment reinforcement.
Casting: using high performance cast aluminum alloy, heat treatment reinforcement.
Aluminium alloy plate are 2000 series, 5000 series and 6000 series alloys.
Department of 2000 alloy is a kind of heat treatment can be reinforced aluminum alloy, with excellent forging resistance, high strength and good welding performance, good baking reinforcement effect, but its corrosion resistance is worse than other series of aluminum alloy. At present, 2036 and 2022 alloy has been used for automobile body panel.
Department of 5000 alloy is a kind of reinforced aluminum alloy heat treatment, with good corrosion resistance and welding performance, but the annealing conditions in machining deformation may be produced when the flow lines and delayed yield, so it is mainly used for automobile body panels within complex shape parts.
6000 series belong to the heat treatment can be reinforced aluminum alloy, alloy has high strength, good plasticity and excellent corrosion resistance. Compared with steel plate, the 6000 series 2 t4 state board of yield strength and tensile strength, even more than steel hardening coefficient. At present, 6009, 6010 and 6016 aluminum alloy because of its plasticity is good, and can be realized in the process of forming after spray paint baking artificial aging and characteristics such as high strength, is used in the automobile body plate and plate. The audi A8 car plate adopted the department of aluminum alloy. In addition, in order to enhance the buffering capacity of car and increase the fatigue strength, Germany VAW, Japan KOK, China southwest aluminum industry are based on this series alloy, research and development of high-performance automotive aluminum and aluminum. At present, the 6000 series alloy as the main panels.
