Density of Common Magnesium Alloys
Magnesium alloys are among the lightest structural materials due to their relatively low density compared to many other metals. The density of pure magnesium is approximately 1738 kg/m3. However, when combined with other elements such as aluminum, zinc, manganese, or others, the resulting magnesium alloys can have varying densities depending on their exact composition.
The following table provides a comprehensive list of density values for various magnesium alloys at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
