DENSITY OF ALUMINUM ALLOYS




Density of aluminum alloys is about 0.1 lb/in3 [2,700 kg/m3] on average and doesn’t vary much because alloying elements constitute a small portion of the composition. Since density is the weighted average of the densities of the elements that constitute the alloy, the 5xxx and 6xxx series aluminum alloys are the lightest because magnesium is the lightest of the main alloying elements. The actual density of wrought aluminum alloys is usually close to the nominal value, but the density of aluminum castings is about 95% to 100% of the theoretical density value due to porosity.

Aluminum and aluminum alloys are characterized by a relatively low density compared to steel.
