Ferro-tungsten is an alloy of tungsten (68–72% or 78–86%) and molybdenum (up to 7%), the rest is Fe and impurities. Ferro-tungsten is obtained by smelting from wolframite and scheelite concentrates. Ferro-tungsten is one of the most important alloying elements in the production of special steel grades. It increases their heat resistance and resistance to tempering. In addition, ferrotungsten increases the hardness and wear resistance of alloys, increases the ultimate strength and yield strength of steel with a slight decrease in the relative elongation. Therefore, it is mainly used in the production of tool steels (for example, high-speed) and high-temperature alloys.

Type by purpose

Ferrotungsten is used in ferrous metallurgy for alloying steel and alloys. Ferromolybdenum is used instead of pure molybdenum when alloying steel, cast iron and alloys. In ferrous metallurgy, ferrovanadium is used in alloying steel, alloys and cast irons to obtain a fine-crystalline structure, increase the impact strength and resistance of steel against alternating loads, and increase hardenability. Nitrided ferrovanadium is intended for alloying high-speed, low-alloy, stainless, frost-resistant steels with vanadium and nitrogen. Ferroniobium is used in the smelting of structural steel and heat-resistant alloys.
