· Fe2W

Fe2W is an intermetallic compound composed of iron and tungsten, belonging to the class of binary metal compounds that combine a transition metal base with refractory tungsten. This material exhibits high stiffness and density, making it of interest in research contexts focused on wear-resistant coatings, structural reinforcement, and high-temperature applications where the hardness of tungsten and the processability of iron-based systems can be leveraged. Fe2W is not a common commercial alloy but rather represents a research-phase intermetallic that may be explored for specialized industrial uses where extreme hardness, thermal stability, or wear resistance justify the complexity of processing such compounds.
