0.05 to 0.2% vanadium and manganese in a concentration equal to 1/4 to 2/3 of the iron concentration are added to an aluminum wrought alloy containing 0.3-1.0% Mg, 0.3-1.2% Si, 0.1-0.5% Fe and up to 0.4% Cu. This alloy is employed mainly for the manufacture of extruded products.

Aluminum alloy

An aluminum alloy of the AlCu type containing cadmium and manganese exhibits an optimum combination of strength, toughness and corrosion resistance. The alloy contains 4.0 to 5.0% copper, 0.1 to 0.2% cadmium and 0.2 to 1.0% manganese. The alloy is suitable for the production of high strength, tough and corrosion resistant extrusion products.
