Grade: industrial aluminum 1A80 Features and Scope: For industrial aluminum with high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but low intensity, heat treatment can not strengthen machinability bad; to welding, hydrogen bonding and contact welding, brazing is not easy; easy to withstand the pressures processing and extension, bending. The chemical composition of aluminum Al: 99.50 Silicon Si: ≤0.25 copper Cu: ≤0.05 magnesium Mg: ≤0.05 Zinc Zn: ≤0.07 Mn Mn: ≤0.05 Titanium Ti: ≤0.05 iron Fe: 0.000 ~ 0.400 Note: Single: ≤0.03 Mechanical Properties : Tensile strength σb (MPa): ≤137 Elongation δ10 (%): ≤3
