· JVASP-112464· Lu2Au

Lu2Au is an intermetallic compound combining lutetium and gold, belonging to the rare earth–noble metal alloy family. This material exists primarily in research and specialized applications rather than mainstream industrial use, with potential applications in high-temperature systems, electronic devices, and catalytic applications due to the unique combination of rare earth and noble metal properties. Engineers would consider Lu2Au for niche applications requiring the chemical stability of gold with the electronic or thermal characteristics that lutetium intermetallics provide, though practical adoption remains limited pending further development and characterization.

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.
