A molybdenum-iron alloy produced in the electric furnace or by a thermite process; used to introduce molybdenum into iron or steel alloys, and as a coating material on welding rods.

The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



a ferroalloy containing approximately 60 percent molybdenum, the remainder consisting of Fe and impurities. Ferromolybdenum is produced by the nonfurnace silicothermic process, here involving the addition of aluminum from roasted molybdenite concentrate. It is used in the smelting of structural steel and heat-resistant alloys.

Next time you see a report that ferromolybdenum imports are down unexplainably, keep in mind that another company on the list above has probably joined the program.
If increase of titanium content in ferroalloy enables reduction of its density and melting point of the alloy changes insignificantly [8], in melting of ferrovanadium, ferroniobium and ferromolybdenum sharp increase of temperature of alloys is observed as content of the main alloying element increases, which causes reduction of the pool dimensions and need to reduce optimum mass of the metal being remolten.
