· JVASP-63747· HoCu4Au

HoCu4Au is a ternary intermetallic compound composed of holmium, copper, and gold, belonging to the rare-earth metal alloy family. This material is primarily of research and academic interest rather than established industrial production, with potential applications in high-density electronic devices, magnetoelectric systems, and specialized functional alloys where rare-earth elements provide unique magnetic or electronic properties. Engineers would consider this material in emerging technologies requiring precise control of magnetic moments or in niche applications where the specific combination of rare-earth and noble metal properties offers advantages over conventional alternatives.

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.
