Ferrotungsten (FeW) is an alloy containing iron and tungsten. This ferroalloy is used for the production of tungsten-containing steels. Ferro tungsten typically consists of either 75-82% or 70-75% tungsten, depending on its grade. This master alloy is a robust alloy with a high melting point, and the addition of tungsten overcomes iron’s brittleness, making it a durable material.
Typical Applications

Ferrotungsten is used in fabricating superalloys. It is commonly used for aerospace functions and the welding industry, and the electronics industry. Ferrotungsten is often used in metallic films, wiring, circuitry, and electron microscopes.
