· JVASP-49158· Y3AlNi8

Y3AlNi8 is an intermetallic compound combining yttrium, aluminum, and nickel, belonging to the rare-earth intermetallic family. This material is primarily of research and development interest rather than established industrial production, with potential applications in high-temperature structural materials and advanced alloy systems where rare-earth strengthening effects are sought. The combination of yttrium's high melting point characteristics with aluminum and nickel suggests use in aerospace or thermal-barrier contexts, though engineering adoption remains limited pending demonstration of cost-effectiveness and processability advantages over conventional superalloys.

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.
