· TmNi5

TmNi5 is an intermetallic compound composed of thulium and nickel, belonging to the rare-earth metal intermetallic family. This material is primarily investigated in research contexts for hydrogen storage applications and as a potential component in advanced functional materials, where rare-earth intermetallics offer unique electronic and structural properties that differ significantly from conventional alloys. While not yet widely deployed in production engineering, TmNi5 represents the broader class of rare-earth nickel intermetallics being explored for next-generation energy storage and catalytic systems.
