1070 Aluminum Alloy is a commercially pure aluminum alloy in the 1000 series with minimum 99.5% aluminum content and excellent corrosion resistance, electrical conductivity, weldability, and formability. Due to its high purity and lightweight nature, it is widely used in electrical, construction, automotive, and industrial applications where high ductility and conductivity are required rather than high strength.
