· JVASP-38793· YbFeB4

YbFeB4 is an intermetallic compound in the rare-earth iron boride family, combining ytterbium, iron, and boron elements. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in permanent magnet systems and high-temperature structural components where rare-earth strengthening is beneficial. The ytterbium-iron-boron system is explored for its potential to offer alternative rare-earth magnetic performance or improved thermal stability compared to conventional RE-Fe-B magnets, though commercialization and large-scale engineering use remain limited.

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.
