Ferrotungsten (FeW) is an alloy consisting of iron and tungsten. This alloy is a robust, unique metal with numerous applications. Ferrotungsten typically consists of either 75-82% or 70-75% tungsten, depending on its grade. Combining iron and tungsten creates a material with an extremely high melting point, second only to the melting point of carbon. Tungsten’s natural strength overcomes the iron’s brittleness and makes ferrotungsten a valuable part of many superalloys.

This metal’s unique properties are highly desirable for several products and uses. Adding ferrotungsten to any alloy raises the metal’s melting point, which is a useful feature for demanding applications. Ferrotungsten and tungsten-containing steel are common elements in aerospace functions and the welding industry, both of which require durable materials. Tungsten’s electrical conduction capabilities also make it valuable in the electronics industry. Companies and manufacturers often use ferrotungsten in metallic films and wiring, circuitry, electron microscopes and more.
