Ferro Tungsten By New Company-carlos Xie

erro 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.
