Ferro Tungsten is prepared from wolframite by carbon reduction in an electric furnace. It is mainly used as alloying element additive for tungsten containing alloy steel (such as high-speed steel). There are three kinds of ferrotungsten produced in China, including w701, W702 and w65, with a tungsten content of about 65 ~ 70%. Due to the high melting point, it cannot flow out of the liquid, so it is produced by caking method or iron extraction method.
