Y2AlNi2
metal· JVASP-85373· Y2AlNi2
Y2AlNi2 is an intermetallic compound composed of yttrium, aluminum, and nickel, belonging to the family of rare-earth-based intermetallics. This material is primarily of research and development interest rather than established industrial production, being investigated for high-temperature structural applications where conventional alloys reach performance limits. The yttrium content and intermetallic structure suggest potential use in aerospace and advanced energy systems, though Y2AlNi2 remains largely in the experimental phase with development focused on understanding its creep resistance, oxidation behavior, and mechanical properties at elevated temperatures.

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.
