Some knowledge about magnesium
Magnesium is one of the most abundant light metal elements on earth. The density of magnesium is 1.74, only 2/3 of that of aluminum, 2/5 of titanium and 1/4 of steel. Magnesium alloy is 36% lighter than aluminum alloy, Light 73%, 77% lighter than steel. Magnesium has a specific strength, high specific stiffness, good thermal conductivity, and has excellent electromagnetic shielding, damping, damping, cutting processability and low processing costs and easy recovery. Magnesium alloy than the strength of aluminum and steel, slightly lower than the highest strength than the fiber reinforced plastic; than the stiffness and aluminum and steel, much higher than the fiber reinforced plastic; wear resistance much better than low carbon steel, Has exceeded the die-casting aluminum alloy A380; damping performance, magnetic shielding performance is far better than aluminum.
Magnesium is widely distributed in nature, resources are abundant, the most important source of magnesium is seawater, salt lake brine in the magnesium chloride and carnallite and carbonate form of magnesite and dolomite.
Metal magnesium production methods are molten salt electrolysis and thermal reduction method. The world's magnesium production with these two methods, accounting for 80% and 20%. Molten salt electrolysis magnesium oxide, including magnesium production and electrolysis magnesium two steps; silicon thermal reduction method of magnesium and Pidgeon method and Magnet method two.
