Y3Au2
metal· JVASP-63424· Y3Au2
Y3Au2 is an intermetallic compound combining yttrium and gold, belonging to the rare-earth metal family of advanced alloys. This material is primarily of research and development interest rather than established industrial production, explored for specialized applications where the combination of rare-earth properties and gold's chemical nobility offers potential advantages in extreme environments or precision applications. Engineers would consider Y3Au2 in contexts requiring materials with unusual elastic or thermal characteristics, though commercial availability and cost typically limit its use to laboratory investigations, aerospace research, or high-performance electronics development.

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.
