· JVASP-37477· SmNiB4

SmNiB4 is a rare-earth intermetallic compound combining samarium, nickel, and boron, belonging to the class of hard magnetic and refractory metal borides. This material is primarily of research and development interest rather than a mature commercial alloy, explored for its potential in high-temperature magnetic applications and wear-resistant coatings where the combination of rare-earth strengthening and boride hardness could provide advantage over conventional alternatives.

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.
