Li4ZrBe

Li4ZrBe is an experimental intermetallic compound composed of lithium, zirconium, and beryllium. This material belongs to the family of lightweight metal alloys and is primarily of research interest rather than established industrial production. The combination of these elements—particularly the low-density lithium matrix with zirconium and beryllium additions—positions it as a candidate for next-generation aerospace and advanced structural applications where weight reduction and thermal stability are critical, though its practical engineering use remains limited and would require careful evaluation against more mature lightweight alternatives.
