What is 1100 Aluminum
1100 aluminum is a commercially pure aluminum alloy in the 1xxx series, containing at least 99.0% aluminum. It offers excellent corrosion resistance, high thermal and electrical conductivity, and outstanding formability, making it suitable for a wide range of industrial and commercial applications.
Unlike heat-treatable aluminum alloys, 1100 aluminum gains strength primarily through cold working rather than heat treatment. Manufacturers can supply it in various tempers, including O, H12, H14, H18, and H24, to meet different strength and forming requirements.
