Magnesium and magnesium alloys have been employed in a wide variety of structural applications because of their favorable combination of tensile strength 160 to 365 MPa, or 23 to 53 ksi), elastic modulus (45 GPa, or 6.5 × 106 psi), and low density (1.74 g/cm3, which is the lowest density of all structural metals). Magnesium alloys have high strength-to-weight ratios (tensile strength/density), comparable to those of other structural metals. Magnesium has relatively good electrical conductivity (38.6% IACS) and thermal conductivity (154.5 W/m · K, or 89.2 Btu/ft · h · °F) values. It also has a very high damping capacity, that is, the ability to absorb elastic vibrations.
