ErAl7Au3
metal· JVASP-22759· ErAl7Au3
ErAl7Au3 is a ternary intermetallic compound combining erbium, aluminum, and gold—a rare-earth metallic system studied primarily in materials research rather than established industrial production. This material family is of interest for high-temperature applications and specialized alloy development, where the erbium addition can provide creep resistance and the gold component may enhance certain mechanical or electronic properties. Engineers would consider this material in advanced aerospace, electronics, or research contexts where rare-earth intermetallics offer performance advantages over conventional binary alloys, though practical application remains limited pending further development and cost evaluation.

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.
