· JVASP-130017· Pu7W

Pu7W is a plutonium-tungsten alloy combining the nuclear properties of plutonium with tungsten's high density and refractory characteristics. This material is primarily of research and specialized defense/nuclear interest, where the combination of density, thermal stability, and nuclear behavior makes it relevant for specific isotope handling, shielding applications, or nuclear fuel contexts. Engineers encountering this material work in highly restricted domains requiring both materials expertise and appropriate security clearances.

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.
