· JVASP-129979· Pu7Nb

Pu7Nb is a plutonium-niobium metallic alloy, representing a specialized composition within the plutonium alloy family used primarily in nuclear materials research and weapons science. This material is of historical and ongoing interest in nuclear metallurgy for understanding phase stability, mechanical behavior, and corrosion resistance of plutonium systems, though its applications are restricted to government nuclear facilities and authorized research institutions. The addition of niobium to plutonium serves to stabilize specific crystallographic phases and improve workability compared to unalloyed plutonium, making it notable for precision casting and machining in controlled nuclear environments.

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.
