LiBeNi

LiBeNi is a ternary intermetallic compound combining lithium, beryllium, and nickel—a research-grade material studied for its combination of low density (due to lithium content) and stiffness (from beryllium and nickel contributions). This material falls within the family of lightweight structural intermetallics and is primarily of academic and exploratory interest rather than established industrial production. Engineers would consider LiBeNi in specialized applications demanding high specific stiffness and minimal weight, though challenges with beryllium toxicity, manufacturing complexity, and cost typically limit adoption to aerospace research programs, advanced composite reinforcement studies, or next-generation structural applications where conventional aluminum or titanium alloys prove insufficient.
