Magnesium
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).
Magnesium alloy
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.
Advantages of magnesium alloy auto parts
1. Light weight: magnesium alloy is 1/3 lighter than aluminum alloy
and 77% lighter than steel, which is the lightest
structural metal material in common use.
2. High specific strength and strong rigidity: in the same shape,
the rigidity of magnesium alloy products is more than 10
times that of plastics.Under the same rigid conditions, a pound of
magnesium is as strong as 1.8 pounds of aluminum and
2.1 pounds of steel.If ABS plastic is replaced with magnesium
alloy, the weight of the product can be reduced by 36% and
the thickness can be reduced by 64%.
3. Impact resistance: excellent damping shock absorption
performance: magnesium alloy resistance to vibration and
reduce noise performance is excellent, 10-50 times of aluminum
alloy.Magnesium alloy is strong enough to withstand
impact, and its thickness is only 1/3 of that of plastic under the
same resistance.
4. Good creep resistance.
5. In line with environmental protection: can be completely
recycled.
6. Excellent die-casting formability: die-casting can be used to
make parts with complex shapes and shell parts with
ultra-thin thickness up to 0.45mm thick (ABS plastic 1.2-2mm,
aluminum alloy 1.5-2mm).
Can be customized according to customer demand a variety of auto
parts.
