· JVASP-145830· Nb12IrAu3

Nb12IrAu3 is an experimental intermetallic compound combining niobium, iridium, and gold—a high-entropy or complex metallic alloy in the refractory metal family. Research alloys of this type are investigated for extreme-environment applications where conventional superalloys reach their limits, leveraging the high melting points and chemical stability of niobium and iridium combined with the corrosion resistance of gold. Such materials remain primarily in laboratory development rather than production use, with potential relevance where weight, temperature stability, and corrosion resistance must all be optimized simultaneously.

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.
