· JVASP-79408· YErAl2

YErAl2 is an intermetallic compound in the rare-earth aluminum family, combining yttrium and erbium with aluminum to form an ordered crystalline phase. While primarily a research and development material rather than a commercial standard, it represents the class of rare-earth aluminum intermetallics being investigated for high-temperature structural applications where thermal stability and specific strength are critical. Engineers would consider this material for applications requiring exceptional performance at elevated temperatures or where the unique properties of rare-earth-modified aluminum phases offer advantages over conventional alloys.

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.
