Product Overview
Aluminum Plate 3003 is an aluminum-manganese (Al-Mn) alloy belonging to the 3000 series, commonly known as “anti-rust aluminum” (防锈铝). Manganese is the principal alloying element, which increases the strength of the alloy by approximately 20% over pure aluminum 1060 while maintaining excellent formability, weldability, and superior corrosion resistance. Our 3003 aluminum plates are widely used in tanks, cookware, heat exchangers, and general sheet metal work, available in O, H14, H16, H24, H18 and H112 tempers with custom sizes.
