1100 is formed by adding a small amount of copper element to pure aluminum, which has excellent forming processing characteristics, high corrosion resistance, good weldability and electrical conductivity. Widely used in products that require good formability and high corrosion resistance, but low strength requirements, such as chemical equipment, food industry equipment and storage containers, cooking utensils, pressure tanks, thin sheet processing, deep drawing or spinning concave Containers, welding parts, heat exchangers, clock surfaces and plates, nameplates, kitchen utensils, accessories, hardware, reflectors, etc. Chemical Composition Limits wt% Cu Si Fe Mn Mg Zn Cr Ti Pb.Bi Al 0.05-0.2 Si+Fe?1.0 0.05 / 0.1 / / / >99.00 Typical Alloy 1100-H14 Mechanical and Physical Properties (Typical Mechanical & Physical Properties) Weldability Machinability Corrosion resistance Conductivity 20°C (68?)
