Can lid material: 5052 aluminum plate, 3104 aluminum plate
Status: h19
Thickness: 0.208-0.360mm
Width: 800-1730mm
5052 aluminum alloy has good corrosion resistance, weldability, cold workability, and medium strength. Its surface is very bright after coating. It is widely used in the basic lid of functional drinks.
The aluminum alloy 5052 aluminum plate used for can lids has a flat shape and precise thickness control, ensuring a thickness tolerance of ±0.005mm and ensuring stable post-processing.
