Adding the element lead, tin, or bismuth to Al-Mg-Al alloys can also improve their cutting performance. Al-mg-mn alloy 6262 has excellent machinability and corrosion resistance, anodizing oxidation process performance and strength than 2011 alloy, sometimes can be used in place of 2011. It can be strengthened through heat treatment, in T9(solid solution quenching + artificial aging + cold deformation) temper has extremely strong tensile strength and yield strength but the strength is low, can be used for optical instruments and weak current system components, fasteners, valves and pistons.
