3003 aluminum tube is widely used for its corrosion resistance and weldability, in food containers, kitchen utensils, decorative materials, and automotive components. Its surface can be treated for better aesthetics and durability through painting and anodizing. With high strength and ductility, it suits extrusion, welding, and cutting processes.
3000 series aluminum alloy adds Manganese (Mn), which can provide good corrosion resistance and moderate strength after appropriate surface treatment (such as anodizing). Chalco 3003 and 3A21 aluminum tube busbars can be widely used in transmission and transformation systems and wind power generation systems in harsh environments such as humidity.Welcome contact
