Overview of 3003 Aluminum Coil
3003 Aluminum Coil is a widely used aluminum-manganese alloy product in the 3000 series. It offers higher strength than 1000 series pure aluminum while maintaining very good corrosion resistance, formability, and weldability. As a non-heat-treatable alloy, 3003 is mainly strengthened by cold working and is commonly supplied in soft and work-hardened tempers for different fabrication needs.
Because of its balanced performance and economical cost, 3003 aluminum coil is extensively used in roofing, wall cladding, insulation jacketing, cookware, chemical equipment, storage tanks, heat exchangers, and general sheet metal fabrication. It is especially suitable for applications requiring good bending, stamping, spinning, and deep drawing performance together with reliable resistance to atmospheric and industrial corrosion.
