The purity of electrolytic manganese is very high, its role is to increase the hardness of the metal material, the most widely used manganese copper alloy, manganese aluminum alloy, 200 series stainless steel, manganese in these alloys can improve the strength of the alloy, toughness, wear resistance and corrosion resistance.

Manganese and manganese alloy is one of the indispensable important raw materials for iron and steel industry, aluminum alloy industry, magnetic material industry and chemical industry.

According to industry standard YB/T051-2003 'Electrolytic manganese metal', electrolytic manganese metal is divided into four grades
