· JVASP-94422· UInNi4

UInNi4 is an intermetallic compound composed of uranium, indium, and nickel, representing a research-phase material from the uranium-based alloy family. This compound belongs to an exploratory class of uranium intermetallics studied for potential high-density applications and specialized nuclear or aerospace contexts where extreme density and thermal properties may be leveraged. As a research material rather than a production alloy, UInNi4 remains primarily confined to laboratory and academic investigation, with limited industrial deployment.

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.
