Aplicação

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
