· U2Co21B6

U2Co21B6 is an experimental uranium-cobalt-boron intermetallic compound, representing a research-phase material in the family of high-density metallic systems. This composition combines uranium's extreme density with cobalt and boron additions, likely to tailor hardness, thermal stability, or corrosion resistance for specialized applications. As an early-stage material without established industrial production, U2Co21B6 remains primarily in the laboratory phase, where it is being investigated for applications demanding exceptionally dense, hard materials or for research into phase diagrams and mechanical behavior of uranium-transition metal systems.
