Melting Point of Common Magnesium Alloys

The melting point of magnesium alloys can vary depending on the specific alloy composition. Magnesium itself has a melting point of 650 °C (1202 °F). However, when alloyed with other elements such as aluminum, zinc, or manganese, the melting point of magnesium alloys can be higher or lower than that of pure magnesium.

The table below provides a comprehensive list of melting point values for common magnesium alloys at one atmospheric (atm) pressure. (1 atm = 101,325 Pa)
