Make a difference with Magnesium
• Very light weight : Magnesium is 75% lighter than steel and 33% lighter than aluminium
• Best strength-to-weight ration of any of the structural metals
• Thin wall sections : Sandcast = 0.060" Permanent mold = 0.100"
• Mechanical properties : optimized through heat treatment and melt preparation
• Excellent machinability
• Welds easily
• Excellent dimensional stability
• Highly impact & dent resistant
• Very good damping capacity and low inertia
• Better corrosion resistance than carbon, steel and some aluminium alloys
• Surface protection & painting possible
• Recyclable
• Radion frequencies shielding, non magnetic & thermal conductive
Typical applications of Magnesium
• Automotive parts : Cylinder head covers, clutch housings, steering columns, wheels, instrument panels, valve covers, brackets, hubs ...
• Plane & helicopter components : gear boxes ...
• Computer components
• Bicycles and motorcycles components
• Seat frames
• Housings for military or industrial equipment
• Etc.
