Magnesium

As the lightest structural metal available, magnesium has a high strength-to-weight ratio. With its low modulus of elasticity combined with moderate strength, magnesium alloys can absorb energy elastically, providing excellent dent resistance and high damping capacity. Magnesium has good fatigue resistance and performs particularly well in applications involving a large number of cycles at relatively low stress. The metal is sensitive to stress concentration, however, so notches, sharp corners, and abrupt section changes should be avoided. Magnesium alloys are the easiest of the structural metals to machine and they can be shaped and fabricated by most metalworking processes, including welding.
