Ferro Molybdenum

Ferro molybdenum is an important iron-molybdenum metal alloy, with a molybdenum content of 60-75%. It is the main source for molybdenum alloying of HSLA steel. This alloy is produced by heating a mixture of molybdenum(VI) oxide MoO3, aluminium, and iron. The oxide and the aluminium combine via an alumino-thermic reaction to give molybdenum in situ. The ferromolybdenum can be purified by electron beam melting or used as it is. For alloying with steel the ferromolybdenum is added to molten steel before casting.
