Ferro manganese is an alloy composed of manganese and iron and is produced by blast furnaces or electric furnaces. High carbon ferro manganese produced by electric furnace is mainly used as deoxidizer, desulfurizer and alloy additive for steelmaking.

In addition, with the progress of low carbon ferro manganese production technology, high carbon ferromanganese can also be used to produce low carbon ferre manganese. Ferro manganese is very important in steelmaking and casting. It can improve the hardness, strength and wear resistance of steel, and improving the cutting characteristics of castings.
