· JVASP-37576· YTmAl2

YTmAl₂ is an intermetallic compound composed of yttrium, thulium, and aluminum, belonging to the rare-earth metal aluminide family. This material is primarily of research and developmental interest for high-temperature applications where its intermetallic structure offers potential advantages in strength and oxidation resistance at elevated temperatures. While not yet widely deployed in mainstream engineering, materials in this class are being investigated for aerospace propulsion systems, thermal barrier coatings, and advanced structural applications where rare-earth stabilization can improve creep resistance and chemical stability.

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.
