TbFe3
metal· JVASP-9129· TbFe3
TbFe₃ is an intermetallic compound combining terbium (a rare-earth element) with iron in a 1:3 stoichiometric ratio, forming a rigid metallic phase. This material is primarily of research and specialized industrial interest for its magnetostrictive and magnetocaloric properties, making it valuable in precision actuation systems, magnetic refrigeration devices, and high-performance sensor applications where controlled deformation or magnetic response under applied fields is required. TbFe₃ represents the rare-earth iron intermetallic family, which is engineered for applications demanding strong magneto-mechanical coupling rather than conventional mechanical load-bearing.

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.
