Li2PmAl is an intermetallic compound combining lithium, promethium, and aluminum—a research-stage material within the family of lightweight metallic systems. This composition represents an experimental phase likely under investigation for advanced aerospace or energy storage applications where the combination of low density with metallic stiffness is desirable; however, practical use remains limited due to the radioactive nature of promethium and the material's limited established processing routes.
