Magnesium (Mg), the 12th element on the periodic table, is a basic
earth metal, ahead of aluminum (AL).Magnesium is one
of the most abundant light metallic elements on earth, and is
widely found in magnesite (magnesium carbonate), dolomite
(calcium magnesium carbonate) and carnallite (magnesium potassium
chloride hydrate).
As the lightest structural material, magnesium alloy has low
specific gravity (about 23% of steel and 64% of aluminum) and
high specific strength and stiffness.Good thermal and electrical
conductivity;With good electromagnetic shielding, damping,
shock absorption, and cutting and die casting process performance.
Weight: magnesium alloy is 36% lighter than aluminum alloy, 73%
lighter than zinc, and 77% lighter than steel.
Specific strength: magnesium alloy is equivalent to aluminum alloy
and steel, much higher than fiber reinforced plastics;
Wear resistance: the wear resistance of magnesium alloy is much
higher than that of die-cast aluminum alloy A380;
Damping performance: magnesium alloy is 30 times higher than
aluminum alloy;
Others: magnesium alloy is 200 times higher than plastic in thermal
conductivity, thermal expansion performance is only
half of the plastic.
