Product Description

Ferrotungsten

Product Description

 

FeW 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

Tungsten is a silver gray metal. The atomic weight is 183.85. Electronic structure 4f145d46s2. Density (20 ºC) 19.3g/cm3. Melting point 3400 ºC. Boiling point 5555 ºC. Tungsten forms a solid solution with iron and two intermetallic compounds, Fe2W and Fe3W2 or Fe7W6, but they are unstable at high temperatures. The melting temperature of tungsten iron containing 75% to 85% W is higher than 2500 ºC, so it cannot be discharged from the furnace and can only be produced using the agglomeration method or iron extraction method. The density of industrial ferrotungsten is approximately 15.3g/cm.

Tungsten and iron are the main components of iron alloys. It also contains impurities such as manganese, silicon, carbon, phosphorus, sulfur, copper, tin, and is an alloying agent used in steelmaking. According to different tungsten contents, ferrotungsten is divided into two types: FeW75 (containing 70% to 80% of W, C ≤ 0.20%, P ≤ 0.04%, S ≤ 0.08%, Si ≤ 0.5%, Mn ≤ 0.25%) and FeW80 (containing 75.0% to 85.0% of W, C ≤ 0.20%, P ≤ O.04%, S ≤ 0.08%, Si ≤ 0.7%, and Mn ≤ 0.25%)
