3003 aluminum coils belong to a kind of AL-Mn alloy which is approximately 10% stronger than alloy 1100. 3003 aluminum sheets are non-heat treatable, so the mechanical property is improved by cold processing: it has high plasticity in annealed condition, good plasticity when semi-cold hardening, while low plasticity during cold hardening. It has good corrosion resistance, excellent weldability, but poor machinability. It is mainly used on low load parts working in liquid or gas and require high formability and weldability, such as oil tank, gasoline or lubricate pipe, liquid container, and other low load parts made by deep drawing. Wire rods are used to make rivets.Stainless Seamless Pipe Application: With the excellent rust proof property, 3003 aluminum sheets/coils are appropriate to be used in humid environments like refrigerators or air conditioners ducts, mechanical parts, or external packing. 3003 aluminum coils are also widely applied to ships/vessels, vehicles, autom…
