TaNi₂ is an intermetallic compound formed from tantalum and nickel, combining the high-temperature stability and corrosion resistance of refractory metals with the workability and cost-effectiveness of nickel-based systems. This material is primarily of research and developmental interest in aerospace, high-temperature applications, and advanced coatings where extreme thermal environments and chemical resistance are required. Engineers would consider TaNi₂ as an alternative to pure tantalum or conventional superalloys when weight efficiency, thermal cycling resistance, and oxidation protection at elevated temperatures are critical, though industrial adoption remains limited compared to established nickel superalloys.
