Today, magnesium alloys are in use in a diverse range of markets and applications, and the demand is still growing. Why?

Lowest density of all structural metals. 33% lighter than Aluminum and 75% lighter than steel.
High specific strength (up to 133).
Outstanding dimensional accuracy and stability.
High vibration damping capacity.
Good impact & dent resistance.
Better machine-ability than Aluminum.
High electromagnetic interference reduction.
Excellent for complex shapes and tight tolerances.
Full recyclability.

Magnesium alloys are in use around the world in a variety of different applications. The most common applications are:
• Aircraft and missile components
• Aircraft engine mounts, control hinges, fuel tanks, wings
• Automotive wheels, housings, transmission cases, engine blocks
• Bicycles and other sporting goods equipment
• Equipment for material handling
• Ladders
• Laptops, televisions, cell phones
• Luggage
• Portable power tools, chainsaws, hedge clippers, weed whackers
• Printing and textile machinery
• Steering wheels and columns, seat frames
• a replacement to some engineering plastics.

Casting & Wrought Alloys

In most structural applications, magnesium is alloyed with other metals to improve properties or provide other desired characteristics. Along with magnesium’s multiple alloys, the material can be cast by a variety of methods, including high-pressure die casting, permanent mold casting, sand casting, etc.. In cases where the same alloy is used with different casting processes, the properties of the finished castings will depend on the method.

Magnesium alloy sand castings are used in aerospace components because of their clear weight advantage over Aluminum and other materials. And in general, the alloys that are normally sand cast are also suitable for permanent mold casting. The most prevalent casting method for magnesium is die casting, especially in the automotive field.

Wrought 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. They have a special feature that heir compressive proof strength is smaller than tensile proof strength. After forming, wrought magnesium alloys have a stringy texture in the deformation direction, which increases the tensile proof strength. In compression the proof strength is smaller because of twinning, which happens more easily in compression than in tension in magnesium alloys because of the hexagonal lattice structure.
