Ferrotungsten (FeW), is an alloy consisting of iron and tungsten. Ferrotungsten is a remarkably robust alloy because of its high melting point, tungsten has the second-highest melting point after carbon. By combining iron with tungsten, the tendencies towards brittleness are overcome from the raw state of tungsten, and ferrotungsten is often a major component of popular super alloys.
Ferrotungsten as an additive to the production process of ferrous metals will impart several desirable properties upon the new alloy. One of the primary benefits of adding ferrotungsten to an alloy is to increase the alloy’s melting point, making it suitable for aerospace applications as well as welding applications. Additionally, by adding ferrotungsten to an alloy, one can take advantage of tungsten’s unique electrical capabilities as a conductor. For example, tungsten is used in field emission guns like electron microscopes and in IC chips, as well as metallic films that can replace conventional copper wiring.
For a complete listing of ferrotungsten specifications, see ASTM A144.

Work With The Specialists at McCreath Labs
McCreath Laboratories will send trained, experienced technicians to take a represented sample for you. Whether in bulk or containers, our technicians have the training, tools and experience to collect a representative sample, ensuring that all subsequent laboratory testing is accurate and reliable. With our mobile crushing units, ferrotungsten in lump form can be partially processed on site per the ISO and ASTM standards, increasing efficiency and reducing the amount of material taken off-site.
McCreath Laboratories will employ both classical and advanced in-house techniques in the analysis of ferrotungsten. The techniques have been verified through the use of certified reference materials and some are adopted directly from ASTM or ISO standards. A typical ferrotungsten analysis would be done as follows:
|C||Combustion||LECO CS 744||ASTM E1019|
|P||ICP||Thermo ICAP||In house|
|S||Combustion||LECO CS 744||ASTM E1019|
|Mo||ICP||Thermo ICAP||In house|
|Al||ICP||Thermo ICAP||In house|
