Ferro tungsten 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).

There are three types of ferrotungsten produced in my country: W701, W702, and W65, which contain about 65 to 70% tungsten. Because the melting point is high and it cannot flow out of the liquid, it is produced by the agglomeration method or the iron extraction method.
