Magnesium is a silver-white light alkaline earth metal with active chemical properties. It can react with acids to generate hydrogen and has certain ductility and heat dissipation properties. Magnesium Ingot Mg Ingot 99.9 is the most commom form and regular model of Mg Metal.

It is one of the most abundant elements in the earth’s crust and is widely distributed in nature in the form of magnesite, dolomite, carnallite, etc. Magnesium is also one of the essential elements for the human body.

Magnesium metal has superior properties such as low specific gravity, high strength per unit weight, and high chemical stability. Basically, there are two main methods for producing magnesium ingots: one is electrolysis and the other is smelting.

Electrolysis is the most common production method. It produces magnesium ingots by electrolyzing magnesium salts. The smelting method place magnesium ore and coke in an electric furnace in a certain proportion for smelting. And then, the magnesium ore and coke react to form magnesium metal, which precipitates to form magnesium ingots.

Magnesium has superior properties such as low specific gravity, high strength per unit weight, and high chemical stability. Generally, Mg ingot and Silicon Metal are main adding elements in aluminum alloy. Mg alloys can be used to manufacture aircraft fuselages, engine parts, and other accesories.

Moreover, it have strong effect with oxygen, so it can also used in die-casting and steelmaking desulfurization. Also, as an additive agent in conventional propellants and the production of nodular graphite in cast iron. It is a strong reducing agent for titanium, zirconium, beryllium, uranium, and hafnium production;

Magnesium also used to make photography and optical instruments, etc. Meanwhile, magnesium can be used to produce magnesium fertilizer, promote the absorption and utilization of phosphorus by plants;
