5/10/2021 In 2024 aluminum alloy, these elemental percentages are 4.4% Cu, 1.5% Mg, and 0.6% Mn, nominally. This breakdown explains why 2024 aluminum is known for its high strength because copper, magnesium, and manganese greatly increase the strength of aluminum alloys. This strength comes at a disadvantage, however; the high percentage of copper in

2024 Aluminum Physical Properties. In 2024 aluminum alloy, the alloying elements used significantly increases its strength. This is due to the fact that copper (Cu), magnesium (Mg), and manganese (Mn) are added with a combined elemental percentage of 6.5% – Cu-4.4%, Mg-1.5%, and Mn-0.6%. However, the increase in strength provided by the high
