· Er2 Au2

Er2Au2 is an intermetallic compound composed of erbium and gold, representing a rare-earth/precious-metal system of primary research interest rather than established industrial production. This material family is investigated for potential applications in high-temperature structural uses, electronic devices, and specialized coatings, leveraging the unique electronic and thermal properties that emerge from rare-earth–noble-metal bonding. Engineers considering this compound should recognize it as an emerging or experimental material; its relevance depends on whether your application specifically benefits from rare-earth–gold synergy or requires the niche properties of intermetallic phases not readily available in 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.
