Electrolytic high-purity metal manganese sheet refers to the elemental metal obtained by acid leaching of manganese ore and then sent to the electrolytic cell for electrical analysis. Its purity can reach more than 99.7 ~ 99.9%. Electrolytic production has become the main mode of manganese production. The appearance is like iron, irregular flake, hard and brittle, one side is bright, the other side is rough, silvery white to brown, silvery gray after processing into powder; It is easy to oxidize in the air. In case of dilute acid, it will dissolve and replace hydrogen. When it is slightly higher than room temperature, it can decompose water and release hydrogen. The purity of electrolytic manganese is very high. Its function is to increase the hardness of composite metal materials. The most widely used are manganese copper alloy, manganese aluminum alloy and 200 series stainless steel. Manganese can improve the strength, toughness, wear resistance and corrosion resistance of these alloys. Manganese and manganese alloys are iron and steel industry, aluminum alloy industry, magnetic material industry Chemical industry is one of the indispensable and important raw materials.
