Y3Al7Cu2
metal· Y3Al7Cu2
Y3Al7Cu2 is an intermetallic compound combining yttrium, aluminum, and copper, belonging to the rare-earth aluminum alloy family. This material is primarily of research and development interest for applications requiring high strength-to-weight ratios and thermal stability; it appears in literature on advanced metallic composites and strengthening phases in aluminum alloys rather than as a standalone commercial product. Engineers would consider yttrium-aluminum-copper intermetallics when designing lightweight structural materials or reinforcement phases for high-temperature applications, though commercial adoption remains limited compared to more established aluminum alloy systems.

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.
