1050 aluminum alloy is formed by adding a small amount of copper element to pure aluminum, which has excellent forming and processing characteristics, high corrosion resistance, good weldability and electrical conductivity.
1050 aluminum alloy is widely used in products that do not require high strength, such as chemical instruments, thin plate processing parts, deep drawing or spinning concave vessels, welding parts, heat exchangers, clock surfaces and disks, nameplates, kitchen utensils, decorations, reflective appliances, etc. .
