· Ni2 Ta1

Ni2Ta1 is an intermetallic compound composed of nickel and tantalum in a 2:1 atomic ratio, classified as a semiconductor material. This compound belongs to the family of transition metal intermetallics, which are of significant research interest for high-temperature applications and electronic devices due to the favorable properties imparted by combining refractory tantalum with the ductility-enhancing contribution of nickel. While not yet widely deployed in mainstream industrial applications, Ni2Ta1 and related nickel-tantalum phases are investigated for potential use in aerospace propulsion systems, high-temperature structural components, and advanced electronic or photonic devices where conventional superalloys or semiconductors reach their performance limits.

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.
