Brief Introduction Of Magnesium Material
- Sep 05, 2017 -

Magnesium is a silver-white light metal, less than 2/3 of aluminum, and magnesium alloy strength is very high, as early as before World War II, it in a variety of structures (such as aircraft structural parts) applicability, and become the lightest high-quality metal structural materials. Magnesium in nature is very rich, is the earth's crust after aluminum, iron, is the third most abundant structural metal. Metal magnesium is extracted from magnesite, dolomite, Salt Lake brine and seawater. China's magnesite resources total 5.3 billion tons, dolomite has proven reserves of more than 4 billion tons. Qinghai Salt Lake is also an important source of magnesium smelting in China. The existing reserves of magnesium resources in China are the highest in the world. The primary use of magnesium is to be used as an alloying element, followed by the manufacture of cast and deformed magnesium alloys suitable for structural components, and finally for the desulfurization of Steel. At present melting aluminum alloy almost accounted for the global magnesium dosage Hambi. Magnesium alloys, used as structural components, have not been widely used in the past, except in aerospace applications, because of cost reasons. In order to solve the problem of reducing energy consumption and environmental protection, the automobile industry looks to the magnesium alloy for its lightweight. Magnesium alloys can reduce vehicle weight and fuel consumption. The ratio of high strength and stiffness to aluminum alloy and steel, good casting performance and dimensional stability, easy processing, low scrap rate, impact resistance, damping performance, in reducing noise, vibration, safety and comfort than aluminum and cast iron.
