ErAu3

metal

· ErAu3

ErAu3 is an intermetallic compound composed of erbium and gold, belonging to the rare-earth–noble-metal alloy family. This material is primarily of research and specialized industrial interest, used in applications requiring the combination of rare-earth magnetic or electronic properties with gold's chemical nobility and thermal properties. ErAu3 finds niche applications in high-temperature electronics, thin-film device components, and materials research contexts where rare-earth–gold interactions provide functional advantages unavailable 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.
