· JVASP-16719· YFe2B2

YFe2B2 is an intermetallic compound combining yttrium, iron, and boron, belonging to the family of rare-earth iron borides. This material is primarily of research and specialized industrial interest, developed for high-performance applications where exceptional hardness, thermal stability, and magnetic properties are required. The combination of rare-earth and transition metal elements makes YFe2B2 notable for advanced engineering contexts where conventional steel or standard iron-based alloys cannot meet demanding performance criteria.

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.
