· JVASP-151050· TbCo4B

TbCo₄B is an intermetallic compound combining terbium, cobalt, and boron, belonging to the rare-earth transition metal boride family. This material is primarily of research and development interest rather than established industrial production, with potential applications in permanent magnet systems and high-performance magnetic devices that exploit rare-earth elements' strong magnetic properties. Engineers considering this compound should recognize it as an experimental material whose viability depends on cost, manufacturability, and performance validation against established rare-earth alternatives like NdFeB or SmCo magnets.

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.
