Pure manganese is a hard, brittle, silvery colored, metallic element which exists in three polymorphic forms (alpha, beta and gamma) and has a complicated crystal structure. It resembles iron in being moderately reactive and dissolving in cold, dilute non-oxidising acids. When exposed to air, manganese forms an extremely stable oxide coating which is not easily reduced. Pure manganese is ferromagnetic after processing. Manganese is not used as the basis of alloys but it is a common constituent of alloys based on other systems, its addition resulting in a significant improvement in the physical and mechanical properties of the resulting alloys.

Manganese powder is a cost effective alloying element with a high hardenability. It is majorly used in powder metallurgy applications such as:

  • a starting material for the preparation of manganese oxide for lithium ion batteries

  • a material used in surface alloying

  • sintering of steel to form manganese steel
