· JVASP-51330· Y2FeB

Y2FeB is an intermetallic compound combining yttrium, iron, and boron, belonging to the rare-earth iron boride family of materials. This compound is primarily of research and developmental interest rather than established in high-volume industrial production, with potential applications in magnetic, structural, and high-temperature material systems where rare-earth strengthening and chemical stability are desired. Engineers would consider Y2FeB in specialized contexts requiring tailored combinations of stiffness, density, and thermal or magnetic performance, particularly in early-stage materials development for aerospace, advanced magnets, or thermal barrier applications.

Export Control

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.
