Magnesium and magnesium alloys
Magnesium (Mg) is the lightest metal.
Alloys are used in structural and non-structural applications.
Typical uses of magnesium alloys are aircraft and missile components.
Also has good vibration-damping characteristics.
Compared with aluminum, magnesium is approximately two-thirds of its weight.
PROPERTIES OF MAGNESIUM :
Specific gravity 1.74
Melts at 651°C
Boiling Point is 1110°C
It is silver white processing high lustre.
Magnesium Wrought alloys
Magnesium alloys for wrought products are classified as non-heat treatable and heat treatable. AZ80A and ZK60A are heat treated by aging the material as fabricated. The strengths are increased substantially but with loss of elongation on aging. M1A and AZ31B sheet are supplied as hot rolled, as cold rolled, and annealed.
The principal wrought manufactures which are commercially available in magnesium alloys include sheet and other flat rolled products, extrusions (bars, rods, solid shapes, hollow shapes, and tubing), forgings, screw-machine stock, and impact extrusions.
Burns easily when being machined

Magnesium Wheel
Used with Aluminium to make lightweight alloys.
Place pieces of magnesium adjacent to buried steel pipelines and water tanks. The magnesium reacts chemically to the elements found in the earth and prevents corrosion of the steel.
