· JVASP-63432· HoNiB4

HoNiB4 is an intermetallic compound combining holmium, nickel, and boron, belonging to the rare-earth transition metal boride family. This material is primarily of research and experimental interest, investigated for potential applications requiring high hardness, thermal stability, or magnetic properties that arise from the combination of rare-earth and early transition metal elements. The boride phase provides potential for wear resistance and elevated-temperature strength, making it a candidate for specialized high-performance applications, though industrial adoption remains limited compared to more established engineering alloys.

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.
