The benefits of magnesium alloy materials
Magnesium is a lightest structural metal, about the two third of the density of aluminum, one fourth of steel, copper and brass.
Magnesium has high reflectivity and can be used for decorative applications
Magnesium can be utilized in structural application due to the high strength Vs weight ratio
Magnesium is with excellent thermal conductivity
Magnesium is with better acoustical deadening (damping) than that of aluminium
Magnesium is with good EMI and RF shielding characteristics
Magnesium can be 100% recyclable (environmentally friendly)
Magnesium has longer tool life than aluminium (for die casting and extursion)
Magnesium alloys materials (per unit) price is amost equal to aluminium
Magnesium is a non-toxic material that human-being need it, it is Bio-compatibility material
Why Magnesium?Magnesiums Advantages
Lightest Structural Metal
With a density of 1.8gcm3, by volume magnesium is 30% lighter than aluminium and 75% lighter than steel.
High Specific Stiffness
For bars with equivalent weight and width, magnesium is 18 times stiffer than steel and double that of aluminium. In practice it is not always possible to increase section thickness to these extents. But with only small increases in cross section it is not possible to redesign parts that offer 20-25% weight savings over aluminium equivalents and 65-70% weight savings when substituting steel designs.
Versatile
Magnesium alloys can be shaped into plate by rolling and extruded into both solid and hollow profiles. These can be further shaped using forging, pressing, bending or simply machining from solid.
Highly Machinable
Magnesium alloys are the easiest of all structural metals to machine.
Advantages include:
Low power consumption (45% less than aluminium)
Fast machining rate (55%)
Excellent surface finish
Reduced tool wear
Well broken chips
High Strength
Alloys are available that have comparable properties with other structural metals – with the added advantage of superior performance at elevated temperatures (good creep resistance and tensile strength).
EMI/RFI Shielding
Has inherent screening properties, useful for electronic enclosures and has good thermal conductivity for heat dissipation.
Vibration Damping
Magnesium alloys have excellent vibration damping properties.
Corrosion Resistance
Modern alloys have good corrosion resistance. For more severe environments there are a range of surface passivation and top coat treatments commercially available.
