3003, an Al-Mn alloy, which is the most widely used rust-proof aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum) and it cannot be strengthened by heat treatment. Therefore, cold processing method is used to improve its mechanical properties. In the annealed state, high plasticity. When the semi-cold hardening, the plasticity is still good, when the cold hardening, bad plasticity and machinability, but good corrosion resistance and weldability. For low load parts that require high plasticity and good weldability to work in liquid or gaseous media. Such as 3003H24 fuel tank, gasoline or lubricant conduit, various liquid containers and other deep-drawn low-load parts, and wire rods are used to make rivets. Bending performance: The conventional 90-degree bend, and below 0.8 can meet the requirement of short-edge roofing application. Coating Application: Roofing sheet, ceiling, interior decoration,curtain wall, ACP.
