YAu
metal· YAu
YAu is an intermetallic compound combining yttrium and gold, representing a rare-earth/precious-metal system of primarily research interest. This material belongs to the family of intermetallic compounds that exhibit high stiffness and low density characteristics, making it relevant for advanced structural and functional applications where conventional metals fall short. While not yet established in high-volume industrial production, YAu and related yttrium-gold phases are explored in materials science for applications requiring exceptional mechanical stability, thermal management, or specialized electronic 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.
