Manganese | Mn (Element) - PubChem

Manganese is used to form many important alloys. Manganese improves rolling and forging qualities in steel, along with adding strength, stiffness, wear resistance, hardness. With aluminum and antimony, and especially with small amounts of copper, it forms highly ferromagnetic alloys. Manganese metal is ferromagnetic only after special treatment.
