5083 5182 aluminum plate for car trunk lid
To cut down on fuel usage, automakers leverage lightweight materials in car body construction. Aluminum alloy, renowned for its superior performance and economic feasibility, has emerged as the preferred choice for lightweight vehicles. Pivotal to this lightweighting process are the opening and closing components, specifically the four doors, front hood, and trunk lid. Among these, 5083/5182 aluminum plate stands out as a commonly adopted alloy in the automotive sector, particularly for trunk lid applications.
5083 Aluminum Sheet for Automotive Trunk Lid Applications: The 5083 aluminum alloy exhibits robust rust-proofing capabilities, coupled with superior strength, fatigue endurance, plasticity, and corrosion resistance. Notably, this alloy does not respond to heat treatment for strengthening. When semi-cold worked, it retains excellent plasticity, but once fully cold worked, it displays lower plasticity while maintaining its commendable corrosion resistance and weldability. Its machining properties are somewhat limited, yet it is polishable. Predominantly, the 5083 aluminum plate finds application in welding components that demand high plasticity and weldability, such as those found in ship hulls, vehicles, automotive, and aircraft panels. It serves as a preferred choice for lightweight automotive aluminum plates.
The 5182 aluminum plate intended for automotive trunk lids shares similarities with the 5083 aluminum plate, belonging to the Al-Mg alloy family and boasting robust corrosion resistance, stellar weldability, favorable cold workability, and moderate strength. Nonetheless, the 5182 aluminum plate edges out the 5083 aluminum alloy in terms of both tensile and yield strength. Enhanced by a slight addition of Si, the 5182 aluminum plate excels in welding performance, accommodating techniques such as gas welding, argon arc welding, spot welding, and seam welding. Moreover, its ease of painting and coating makes it a prime choice for achieving the desired aesthetic appeal and finish of trunk lids.
