LuFe2 is an intermetallic compound composed of lutetium and iron, belonging to the rare-earth iron intermetallic family. This material is primarily of research and development interest rather than established industrial production, with applications explored in magnetic devices, high-strength structural composites, and specialized alloy systems that leverage rare-earth–transition metal interactions. Engineers consider LuFe2 and similar compounds when designing systems requiring exceptional stiffness-to-weight ratios, magnetic properties, or extreme temperature stability, though commercial adoption remains limited due to cost, scarcity of lutetium, and processing challenges.
