1100 Aluminum Coil
1100 is a commercially pure aluminum alloy, containing 99.0% to 99.95% aluminum, with small amounts of silicon, iron, copper, manganese, zinc, titanium, and other elements.
1100 aluminum coil is the highest industrial purity aluminum, and due to its controlled copper content, it is also the strongest alloy in the 1xxx series, while retaining most of the characteristics of pure aluminum: excellent electrical conductivity, corrosion resistance, and formability.
1100 aluminum coil cannot be strengthened by heat treatment. Due to its excellent plasticity, corrosion resistance, and electrical and thermal conductivity, it is widely used in construction, industry, and daily consumer fields.
1100 aluminum coil is a soft, versatile, and corrosion-resistant alloy suitable for forming-intensive applications requiring high electrical conductivity and weldability (but not strength). It is available in various tempers, thicknesses, and surface treatments, and is widely used in HVAC, chemical/food processing, decorative trims, and metal products.
1100 aluminum coil remains indispensable for applications prioritizing formability and corrosion resistance over high strength. Its adaptability in different tempers and compatibility with various manufacturing processes have consolidated its status in heat treatment, construction, and consumer sectors.
