· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
