LiBeAu2

LiBeAu2 is an intermetallic compound combining lithium, beryllium, and gold—a rare ternary metal system primarily of research interest rather than established industrial production. This material belongs to the family of lightweight intermetallic alloys and represents an experimental composition that combines the low density of lithium and beryllium with gold's chemical stability, though such systems remain largely confined to academic study due to manufacturing challenges and cost constraints. Applications would theoretically target niche high-performance sectors where extreme lightness, chemical inertness, and thermal properties intersect, but practical engineering use is not well established.
