Ferrotungsten is a ferroalloy of tungsten and iron, which is massively used in ferrous metallurgy during alloying of steel and other alloys. The mass fraction of tungsten is 60-85%, up to 7% of molybdenum other impurities. Ferrotungsten is very difficult to melt, under normal conditions it has chemical resistance.

Ferrotungsten is a important alloy addititve when produce hardfacing rod or wire. Tungsten can improve the welding coating’s strength and  toughness and also can improve the hardness and anti-wear performance of coating80. As the addition agent of tungsten in steel making and casting, it can improve the hardness, wear resistance and impact strength of steel. For high speed tool steel, alloy tool steel, heat-resistant steel, spring steel, steel product.
