Electrolytic Manganese metal is the main material for producing Trimagananese tetroxide. And for it's high quality and little impurity, it's also an important alloy element for producing stainless steel, high- strength low- alloy steel, Alumino- Managanese alloy. Electrolytic Manganese metal is an indispensable raw material for welding rod, ferrite, permanent magnet alloy element, and manganic salt for medical and chemical plants. The newly- developed decreasing vibration alloy also needs Electrolytic Manganese metal.
