ErAu
metal· ErAu
ErAu is an intermetallic compound combining erbium (a rare-earth element) with gold, forming a metallic material with high density and significant stiffness. This material is primarily of research and specialized industrial interest, particularly in applications requiring the unique properties that rare-earth–gold combinations provide, such as enhanced wear resistance, thermal stability, or specific electronic characteristics. ErAu and similar rare-earth gold intermetallics are investigated for niche applications in high-reliability systems where cost is secondary to performance, though commercial adoption remains limited compared to 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.
