UCu4Au
metal· JVASP-62275· UCu4Au
UCu₄Au is an intermetallic compound combining uranium, copper, and gold in a fixed stoichiometric ratio. This is a specialized research material rather than a commercial engineering alloy, studied primarily for its electronic, magnetic, and structural properties within the uranium alloy family. Intermetallics of this type are of interest in nuclear materials research, aerospace metallurgy, and fundamental condensed-matter physics, where the ordered crystal structure and multi-element composition can yield unusual combinations of strength, thermal stability, or electronic behavior not achievable in single-element metals or conventional solid solutions.

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.
