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.
