· JVASP-90268· YAlCu

YAlCu is a ternary intermetallic compound combining yttrium, aluminum, and copper—a research-phase material belonging to the rare-earth aluminum alloy family. While not yet widely commercialized, this composition is investigated for potential applications requiring lightweight, high-strength properties at elevated temperatures, leveraging yttrium's role as a strengthening element in aluminum-based systems. Engineers considering YAlCu would typically be exploring advanced aerospace or specialty applications where conventional aluminum alloys reach performance limits, though material availability and manufacturing processes remain developmental.

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.
