· YAu3

YAu3 is an intermetallic compound composed of yttrium and gold, belonging to the rare-earth gold alloy family. This material is primarily of research and specialized applications interest, valued for its unique combination of rare-earth and noble metal properties that confer potential high-temperature stability, corrosion resistance, and specialized electronic or catalytic characteristics. Engineers consider YAu3 for niche applications requiring the synergistic benefits of yttrium's reactivity and lattice-modifying effects combined with gold's chemical inertness and conductive properties.

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.
