Ferrotungsten
Ferrotungsten usually appears in lumps with a silvery-gray metallic luster.
It is mainly produced by two methods: the electric furnace process and the aluminothermic process. In the electric furnace process, raw materials such as tungsten concentrate, coke, and iron scraps are charged into an electric furnace for reduction at high temperatures. In the aluminothermic process, a violent exothermic reaction between aluminum and tungsten oxide is used to produce ferrotungsten.
Common Grades: FeW70 / FeW80W Equivalent Basis: 70% W basis
Applications:
Steel Industry: As a key alloy additive in the production of high-speed steels, tool steels, and die steels. It improves the hardness, strength, wear resistance, and red hardness of steel, enabling it to maintain excellent cutting performance and wear resistance even at high temperatures.
Cemented Carbides: Used to manufacture cemented carbide tools, drills, and dies. It significantly increases the hardness and wear resistance of cemented carbides, allowing them to handle high-speed cutting and machining of difficult-to-process materials.
Other Fields: Also applied in the production of special high-temperature alloys, magnetic materials, and certain components in the electronics industry to enhance material performance.
Packaging & Storage: Packed in iron drums (100kg, 250kg, or 500kg per drum). It is moisture-sensitive and must be stored in a dry, well-ventilated environment.
