TmFeB4
metal· JVASP-116585· TmFeB4
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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
