YAlS
metal· JVASP-139497· YAlS
YAlS is an intermetallic compound combining yttrium, aluminum, and sulfur, representing a specialized material from the rare-earth intermetallic family. While not widely established in mainstream industrial production, materials in this compositional space are investigated for potential applications requiring lightweight structures combined with thermal stability, particularly in research contexts exploring advanced ceramics and high-temperature applications. Engineers would consider YAlS primarily in experimental or specialized aerospace and materials research programs where conventional aluminum alloys or ceramics prove insufficient.

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.
