Ferro Tungsten

     The Ferro Tungsten ferroalloy series is an alloy composed of tungsten and iron and is used as an alloy additive for steelmaking. Commonly used ferrotungsten contains 70% and 80% tungsten.
     Ferrotungsten is produced from tungsten manganese ore by reducing it with carbon in an electric furnace. Mainly used as alloying element additive for tungsten-containing alloy steel (such as high-speed steel).

 

 

ZhenAn Ferro Tungsten 70

 

 

     Ferro Tungsten 70 is a silver-gray metal. The atomic weight is 183.85. Electronic structure 4f145d46s2. Density (20℃) 19.3g/cm3. Melting point 3400℃. Boiling point 5555℃. 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 ferrotungsten containing 75% to 85% W is higher than 2500°C, so Ferrotungsten cannot be discharged from the furnace and can only be produced by the accumulation method or the iron extraction method. The density of industrial ferrotungsten is about 15.3g/cm.

 

     Ferrotungsten 80 is an iron alloy mainly composed of tungsten and iron. It also contains manganese, silicon, carbon, phosphorus, sulfur, copper, tin and other impurities, and is an alloying agent used in steelmaking.

    According to the different tungsten content, ferrotungsten is divided into: FeW75 (containing W70% ~ 80%, C ≤ 0.20%, P ≤ 0.04%, S ≤ 0.08%, Si ≤ 0.5%, Mn ≤ 0.25%) and FeW80 (containing W75.0%～85.0%, C≤0.20%, P≤O.04%, S≤0.08%, Si≤0.7% and Mn≤0.25%).

     Ferrotungsten 70 80 are used as an additive for tungsten in steelmaking and casting. Tungsten is one of the most important alloying elements in the production of special steel. Tungsten can not only reduce the elongation of steel to a small extent, but also increase the strength limit and yield point of steel.

     It can also improve the hardness and wear resistance of steel. Of particular importance is the good influence of tungsten on the high-temperature mechanical properties of steel, which improves heat resistance and tempering stability.
