Ferrotungsten is an alloy of tungsten and iron. It is used in steel making and casting as an additive for tungsten, which is one of the most important alloying elements in the production of special steels. 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. The most common method of producing ferrotungsten is the “blocking method”, which uses carbon to reduce the oxides in the concentrate in an electric furnace, and then removes the solidified metal blocks from the furnace. There are also iron digging methods and thermite method.

There are two commonly used ferrotungsten: 70% and 80%. Ferrotungsten is mainly used as an additive for alloying elements in tungsten alloy steel (such as high-speed steel). Ferrotungsten is a steel making alloy agent mainly composed of tungsten and iron. It also contains impurities such as manganese, silicon, carbon, phosphorus, sulfur, copper, and tin. Ferrotungsten is produced from wolframite by carbon reduction in an electric furnace. Mainly used as alloy element additive for tungsten-containing alloy steel (such as high-speed steel). As an experienced manufacturer in China, Zhenan provides high quality ferrotungsten. Our ferrotungsten is tested at every stage to ensure physical and chemical performance.
