Ta₂Ni is an intermetallic compound in the tantalum-nickel system, combining refractory metal and transition metal properties. While primarily a research material rather than a commodity engineering alloy, it belongs to a family of high-strength intermetallics studied for extreme-environment applications where both stiffness and density control are critical. The tantalum-nickel system is explored for aerospace and high-temperature applications, leveraging tantalum's exceptional corrosion resistance and refractory character alongside nickel's ductility contribution.
