· JVASP-102740· HoBeCu4

HoBeCu4 is a quaternary intermetallic compound combining holmium, beryllium, and copper in a fixed stoichiometric ratio. This material belongs to the rare-earth beryllium-copper intermetallic family, primarily investigated for specialized high-performance applications where unusual combinations of thermal, electrical, or magnetic properties are required. Industrial applications remain limited and largely experimental; the material is typically evaluated in research contexts for potential use in high-temperature electronics, neutron absorption systems, or advanced composite reinforcement where the rare-earth and beryllium constituents offer synergistic benefits.
