Ferro-tungsten iron alloy series (tungsten content: 70%-80%) is an alloy composed of tungsten and iron, which is used as an alloy additive for steelmaking. Commonly used ferrotungsten contains 70% tungsten and 80% tungsten. Ferrotungsten is prepared from wolframite by carbon reduction in an electric furnace. Mainly used as alloying element additive for tungsten-containing alloy steel (such as high-speed steel). There are three varieties of ferrotungsten produced in my country, including W701, W702, and W65, and the tungsten content is about 65-70%. Due to its high melting point, it cannot flow out in a liquid state, so it is produced by agglomeration method or iron extraction method.
