· JVASP-62212· Er2Au

Er₂Au is an intermetallic compound combining erbium (a rare-earth element) with gold, forming a brittle metallic phase typically studied in rare-earth–precious-metal systems. This material belongs to the family of rare-earth intermetallics and is primarily of research interest rather than established industrial production, with potential applications in high-temperature materials, magnetic devices, and advanced alloy development where rare-earth strengthening and gold's corrosion resistance may be exploited together.

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.
