Nb₃Au is an intermetallic compound formed between niobium and gold, belonging to the family of refractory metal intermetallics. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, studied for applications requiring high stiffness, good thermal stability, and corrosion resistance in demanding environments. It finds use in superconductive applications, high-temperature structural components, and wear-resistant coatings where the combination of refractory properties and noble-metal corrosion resistance provides advantages over conventional alloys.
