Co3W is an intermetallic compound combining cobalt and tungsten, belonging to the family of refractory metal intermetallics. This material is primarily of research and experimental interest, studied for applications requiring high hardness, thermal stability, and wear resistance in extreme environments. Co–W intermetallics are investigated as potential candidates for cutting tool coatings, wear-resistant surfaces, and high-temperature structural applications where the high density and stiffness of tungsten can be leveraged alongside cobalt's toughness and corrosion resistance.
