· JVASP-21576· TmNi4B

TmNi4B is an intermetallic compound containing thulium, nickel, and boron, belonging to the rare-earth metal boride family. This is a research material studied primarily for its magnetic and thermal properties rather than a widespread industrial material. Materials in this chemical family are investigated for specialized applications requiring high magnetic moments, low-temperature performance, or exceptional hardness, though TmNi4B itself remains largely in the experimental phase without established commercial production.

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.
