Various models can be customized 1. The purity of electrolytic manganese is very high. Its function is to increase the hardness of the composite metal material. Manganese can improve the strength, toughness, wear and corrosion resistance of certain alloys. 2. Manganese is an indispensable additive in the smelting industry. After electrolytic manganese is processed into powder, it is the main raw material for the production of manganese trioxide.
