· JVASP-14594· U

Uranium is a dense, naturally occurring metallic element used primarily in nuclear energy and defense applications. It is valued for its high density and fissile properties in enriched isotopic forms, making it essential for nuclear power generation, research reactors, and specialized military systems. Engineers select uranium for applications requiring extreme density in compact geometries, though its use is highly regulated due to radiological and proliferation concerns.

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.
