Materials: Non-Ferrous Metals
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.
