HoCu4Ag
metal· JVASP-149133· HoCu4Ag
HoCu₄Ag is a quaternary intermetallic compound combining holmium, copper, and silver—a rare-earth metal alloy that sits at the intersection of precious and functional metals. This material is primarily of research interest rather than established industrial use, studied for potential applications requiring the unique combination of rare-earth magnetic properties with copper and silver's thermal and electrical conductivity. Engineers would consider this compound in niche applications demanding specialized electromagnetic or thermal performance, though its practical deployment remains limited by cost, processing complexity, and the nascent state of its characterization.
