The two alloys of aluminum those have same amount of copper or magnesium is A) Duralumin B) Magnalium.
The Duralumin is composed of 95% of aluminum, 4% of copper, 0.5% of magnesium, 0.5% manganese which has high strength and high hardness in comparison with pure aluminum.
Magnalium is an alloy of aluminum composed of (70% to 95%) of aluminum and about (3o to 5%) of magnesium and a less amount of copper and nickel, which is a good corrosion resistance, having better plasticity.
