3003 aluminum coil is a common aluminum manganese (Al-Mn) antirust alloy. It is also an alloy without heat treatment, and its mechanical properties can be improved by conventional cold working. In addition, due to its good corrosion resistance, excellent weldability, formability and other advantages, aluminum coil is often used in packaging, mechanical parts, refrigerators, air conditioning ventilation pipes, or ships, vehicles, pressure vessels, etc. Our aluminium products have smooth surface, small thickness tolerance and good stamping oxidation effect. After testing, the indicators are far beyond the standard indicators, products are guaranteed!
