ferromolybdenum, generally containing 50-60% molybdenum, is used as an alloy additive in steelmaking. Molybdenum iron is an alloy of molybdenum and iron. Its main use is as an additive for molybdenum element in steelmaking.

The melting point of molybdenum is 2615 ℃, the boiling point is 4610 ℃, and the density (20 ℃) is 10.2g/cm. Industrial ferromolybdenum contains about 60% Mo, with a melting temperature of 1800~1900 ℃; The density is about 9.0g/cm.
