1. Mainly used in diamond tools, powder metallurgy and other industries；
2. Manganese powder is an important alloying element for the production of stainless steel, high-strength low-alloy steel, aluminum-manganese alloy, copper-manganese alloy, etc. It is also an indispensable raw material for the production of ferrite, permanent magnet alloy and many manganese salts for pharmaceutical and chemical industries. The newly developed damping alloy also requires metal manganese powder.
