TmFeB4 is an intermetallic compound combining thulium (a rare-earth element), iron, and boron, representing a specialized hard material in the rare-earth metal boride family. While not yet commercially widespread, this material is of research interest for applications requiring high hardness and stiffness in extreme environments; rare-earth borides are being investigated as potential alternatives to tungsten carbide and cubic boron nitride in cutting tools, wear-resistant coatings, and high-temperature structural applications where rare-earth magnetic or thermal properties might offer additional benefits.
