TbCo3B2
metal· JVASP-15130· TbCo3B2
TbCo₃B₂ is an intermetallic compound combining terbium (rare earth), cobalt, and boron—a hard, dense metallic phase typically studied as a constituent in rare-earth cobalt-based alloy systems. This material belongs to the family of rare-earth intermetallics known for high hardness and potential magnetic properties; it is primarily encountered in research and development contexts rather than high-volume production, where it may serve as a strengthening phase in permanent magnets, hard coatings, or wear-resistant composite structures. Engineers consider such phases for extreme-environment applications where conventional alloys cannot withstand combined thermal, mechanical, and corrosive demands.

Export Control
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.
