· JVASP-13751· NdAl4

NdAl₄ is an intermetallic compound in the neodymium-aluminum system, combining a rare-earth element with aluminum to form a brittle metallic phase. This material exists primarily in research and specialized high-performance contexts rather than mainstream manufacturing, valued for its potential in applications requiring high stiffness-to-weight ratios and thermal stability. Engineers consider NdAl₄ in advanced aerospace and Materials Science research where rare-earth intermetallics offer unique electromagnetic, thermal, or structural properties unavailable in conventional aluminum alloys or steels.
