· JVASP-18602· ErInAu

ErInAu is a ternary intermetallic compound composed of erbium, indium, and gold, belonging to the rare-earth metal alloy family. This material is primarily of research and development interest rather than established industrial production, with potential applications in high-temperature structural materials, thermoelectric devices, and electronic components that leverage the unique electronic properties arising from rare-earth–transition metal interactions. Engineers would consider ErInAu in specialized applications where the combination of rare-earth magnetism or electronic effects, coupled with the nobility of gold and the semiconductor properties of indium, offers advantages over conventional 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.
