· JVASP-16825· PuNi

PuNi is an intermetallic compound combining plutonium and nickel, representing a specialized metal system primarily of research and nuclear materials science interest. This material belongs to the actinide-transition metal alloy family and is notable for its very high density, making it relevant to applications requiring compact, dense metallic forms. Due to plutonium's restricted handling and the material's limited commercial availability, PuNi is encountered almost exclusively in nuclear engineering research, materials characterization studies, and specialized defense or energy applications rather than general industrial manufacturing.

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.
