· JVASP-156729· PuAu

PuAu is an intermetallic compound combining plutonium and gold, representing a specialized alloy in the plutonium metallurgy family. This material is primarily of research and historical significance rather than commercial production; it has been studied in nuclear materials science and advanced metallurgy contexts to understand phase behavior, mechanical properties, and potential applications in extreme environments where both density and specific mechanical characteristics are relevant. The Pu-Au system exemplifies fundamental intermetallic research with limited practical engineering deployment due to plutonium's regulatory constraints, radioactive nature, and the material's brittleness typical of many plutonium-based compounds.

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.
