NbAu2
metal· NbAu2
NbAu2 is an intermetallic compound combining niobium and gold in a 1:2 stoichiometric ratio, belonging to the class of high-density metallic intermetallics. This material exhibits significant stiffness and moderate density, making it relevant for specialized applications requiring combination of rigidity and weight efficiency. As an intermetallic compound, NbAu2 is primarily of research and development interest; while bulk applications remain limited, materials in this family are explored for high-temperature structural applications, wear-resistant coatings, and aerospace components where conventional alloys reach performance limits.
