3003 aluminum coil strips

The 3003 aluminum coil strips are Al-Mn alloy with good rust resistance. The strength of the alloy is not high (slightly higher than that of industrial pure aluminum). Because it cannot be heat-treated, cold working is used to improve its mechanical properties.
The 3003 aluminum coil strips are containing 1.2% Mn. It is widely used for forming properties, especially for low temperature equipment, general vessels and building materials.
