Magnesium Alloy Box Shell
1. 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).
2. 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.
3. Application of magnesium alloys
As one of the metal structural parts with the smallest density at
present, magnesium alloy is widely used in aerospace
industry, military industry, transportation (automobile, aircraft,
motorcycle, bicycle), 3C and other fields.
Europe is currently using and development of magnesium alloy
automobile parts for more than 60 kinds of North America
are using and are working on the magnesium alloy automobile parts
has reached more than 100, ford motor company bike
USES 45 mg alloy die casting, Chrysler with 20 mg alloy die
casting, bike with magnesium amount to 20-40 kg.Ford has
used up to 103kg of magnesium alloy parts per car in the 2000
concept model.Ford motor Co. plans to increase the amount
of magnesium it USES in each vehicle to 113 kilograms over the next
20 years, according to a report from before 2010.
According to the report, Japan has successfully processed the
automobile top box of flame retardant magnesium alloy
material (length 200mm × width 670mm × height 270mm, weight about
12.5kg).Compared with the FRP (reinforced plastic)
products on the market, the weight can be reduced by about 25%.
At present, magnesium alloy die casting products are used in
automobile instruments, seat frames, directional operating
system components, engine covers, gearboxes, intake pipes, wheel
hubs, engines and safety components.
