· JVASP-21843· TbNi4B

TbNi4B is an intermetallic compound combining terbium, nickel, and boron, belonging to the rare-earth transition-metal boride family. This is primarily a research material studied for its magnetic and thermal properties rather than a commodity engineering material; it appears in the literature on rare-earth intermetallics used to explore permanent magnet behavior, magnetocaloric effects, and high-temperature structural performance in specialized applications.

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.
