Electrical Conductivity of Common Magnesium Alloys

Magnesium alloys generally exhibit good electrical conductivity. The electrical conductivity of magnesium alloys can vary based on the specific alloy composition and processing methods.

The following table provides a list of electrical conductivity values for common magnesium alloys in both International Annealed Copper Standard (%IACS) and Siemens per meter (S/m) units.

Unless stated otherwise, all values are taken at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
