Product Overview
알루미늄 판 3003 is an aluminum-manganese (Al-Mn) alloy belonging to the 3000 시리즈, 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, 용접성, and superior corrosion resistance. 우리의 3003 aluminum plates are widely used in tanks, cookware, 열교환기, and general sheet metal work, available in O, H14, H16, H24, H18 and H112 tempers with custom sizes.
