· Au1 Cu4 U1

Au1Cu4U1 is an experimental precious metal–uranium alloy combining gold, copper, and uranium in a 1:4:1 atomic ratio. This is a research-phase material not in established industrial production; such gold–copper–uranium systems are primarily of academic interest for studying phase behavior, nuclear metallurgy, or specialized high-density applications where uranium's density and gold's corrosion resistance might be jointly valuable. Engineers would encounter this composition only in laboratory contexts or niche defense/nuclear applications, as the uranium content presents handling, regulatory, and shielding considerations that make it impractical for most commercial products.

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.
