High purity electrolytic manganese metal film, its role is to increase the hardness of metallic materials together, the most widely used are manganese-copper alloy, manganese alloy, manganese in these alloys can improve the tensile strength, toughness, wear resistance and corrosion resistance. Applications of manganese and manganese alloy steel, aluminum industry, magnetic materials industry, chemical industry and other important raw material indispensable. Manganese is an essential industrial smelting additives, electrolytic manganese production after processing into powdered manganese oxide raw materials, magnetic materials widely used in the electronics industry is to use the original manganese oxide production, electronic industry, metallurgy industry and EMM aerospace industry needs. With the continuous development of science and technology and the continuous improvement of productivity, electrolytic manganese metal because of its high purity, low impurity characteristics, has been successful and widely used in steel smelting, nonferrous metallurgy, electronics, chemical industry, environmental protection, food hygiene, welding, aerospace industry and other fields
