Ta2Ni
metal· Ta2Ni
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.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
