· JVASP-123183· Er3Au

Er3Au is an intermetallic compound composed of erbium and gold, belonging to the rare-earth metal alloy family. This material is primarily of research and experimental interest rather than established industrial production, with potential applications in high-temperature electronics, specialized coatings, and rare-earth metallurgy where the combination of erbium's thermal and magnetic properties with gold's chemical stability and conductivity may offer advantages. Engineers would consider Er3Au in advanced materials development contexts where conventional alloys cannot meet extreme thermal, chemical, or functional requirements, though material availability and manufacturing maturity remain significant practical constraints compared to standard engineering alloys.

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.
