Ferro Tungsten belongs to ferroalloy series (containing tungsten: 70%-80%), an alloy composed of tungsten and iron, used as an alloy additive for steelmaking. The commonly used tungsten iron is tungsten containing 70% and 80%.
Tungsten and iron are the main components of the iron alloy. It also contains manganese, silicon, Carbon, phosphorus, sulfur, copper, tin and other impurities, and is an alloying agent for steelmaking. According to different amounts of tungsten, the tungsten and iron are divided into: FeW75 (including W70% ~ 80%, C ≤ 0.20%, P ≤ 0.04%, S ≤ 0.08%, Si ≤ 0.5%, Mn ≤ 0.25%) and FeW80 (including W75.0%~85.0%, C≤0.20%, P≤O.04%, S≤0.08%, Si≤0.7% and Mn≤0.25%).
