What is Magnesium Alloys?

Magnesium alloy is magnesium as the main component, while adding other elements of the alloy, its density is low(1.8g/cm3), is 2/3 of aluminum, is 1/4 of iron. Melting point is 650 degree. High strength, good rigidity, good thermal dissipation, good shock absorption, good corrosion resistance of organic and alkali, magnesium alloy because of the filling of other elements, so the flammability is lower than magnesium. Now on the market magnesium alloy, mainly divided into three categories, magnesium-aluminum alloy, magnesium-manganese alloy and magnesium-zinc alloy.

Application: Magnesium alloy is widely used in automotive industry to achieve light weight; such as Engine, Gearbox,wheels; also used on Aircraft,laptop and bicycle frame and so on.


In short, magnesium alloy has many advantages, with new energy vehicles and lightweight design, more and more parts to use magnesium alloy, although magnesium alloy is flammable, but for the die-casting factory, strict management and production process, but also can well control the risk of flammability, if you have magnesium alloy die-casting project, or die-casting materials, please contact us
