· JVASP-59503· UNi2

UNi2 is an intermetallic compound based on uranium and nickel, representing a high-density metallic material from the uranium alloy family. It is primarily of research and specialized industrial interest, used in applications where extreme density, nuclear properties, or specific thermal characteristics are critical requirements. The uranium-nickel system offers potential for advanced nuclear fuel applications, radiation shielding, and specialized high-performance aerospace or defense components where conventional dense metals are insufficient.

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.
