ferrotungsten

Ferrotungsten is a ferroalloy, a type of alloy in which one or more elements are iron-based. Ferrotungsten is a combination of iron and tungsten, typically containing about 70-85% tungsten. It is produced by the aluminothermic reduction of tungsten oxides and iron oxides. This process involves reacting aluminum powder with a mixture of tungsten and iron oxides at high temperatures. The aluminum acts as a reducing agent, separating the metals from their oxides.

The primary use of ferrotungsten is in the production of steel alloys. When added to steel, tungsten significantly increases its hardness, strength, and resistance to high temperatures and wear. This makes ferrotungsten a crucial component in the manufacturing of high-speed steels, tool steels, and wear-resistant alloys. These materials are essential for various industrial applications, including cutting tools, drill bits, molds, and armor plating.

Ferrotungsten also finds application in the production of tungsten metal powder, which has its own diverse uses. The alloy is a convenient and cost-effective way to introduce tungsten into steelmaking processes. The exact composition of ferrotungsten can vary depending on the intended application and the specific manufacturing process employed. It is generally supplied in lump or granular form.
