· JVASP-39267· Lu2AlZn

Lu2AlZn is a ternary intermetallic compound combining lutetium, aluminum, and zinc—representing an emerging class of high-density metallic materials developed primarily in research settings. This material belongs to the family of rare-earth aluminum intermetallics, which are of interest for applications requiring combinations of stiffness, density control, and thermal stability. Lu2AlZn remains largely experimental; its potential lies in specialized high-performance aerospace and advanced structural applications where the unique density-to-stiffness ratio and rare-earth contributions could offer advantages over conventional aluminum alloys or titanium alternatives, though industrial adoption and manufacturing scalability remain underdeveloped.
