· Au1 Cu4 Yb1

Au₁Cu₄Yb₁ is an intermetallic compound combining gold, copper, and ytterbium in a 1:4:1 atomic ratio. This is a research-phase material rather than an established commercial alloy; intermetallic compounds of this type are studied for potential applications in thermoelectric devices, electronic components, and advanced functional materials where the combination of noble metals and rare-earth elements may offer favorable electronic or thermal transport properties.

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.
