· Nb3Au2

Nb3Au2 is an intermetallic compound combining niobium and gold in a fixed stoichiometric ratio, belonging to the family of refractory metal intermetallics. This is primarily a research and specialized material rather than a commodity alloy; it is investigated for high-temperature structural applications and advanced aerospace components where the combination of a refractory metal (niobium) with gold's unique properties—including corrosion resistance and thermal stability—may offer advantages in extreme environments. The material's stiffness and density characteristics make it relevant for applications requiring thermal stability and oxidation resistance at elevated temperatures, though production and cost considerations typically limit it to high-performance niche applications.
