Metal manganese ingot: Electrolytic Manganese sheet has large specific surface and light specific gravity. When used as alloy additive, it has serious burning loss. Therefore, electrolytic manganese sheet is generally re dissolved and cast ingot to make it easy to add and small burning loss. It is mainly used for the production of special steel, non-ferrous metal alloys (Cu, Al alloys, etc.) and as raw materials for the production of soft magnetic materials (high-purity MnCO3, mn3co4), electrode coating, diamond touch coal, etc.
