· JVASP-151985· NbSiNi

NbSiNi is a ternary intermetallic compound combining niobium, silicon, and nickel, belonging to the refractory metal alloy family. This material is primarily investigated in research contexts for high-temperature structural applications where exceptional thermal stability and oxidation resistance are desired, particularly in aerospace propulsion systems and advanced engine components. The niobium-silicon-nickel system offers potential advantages over conventional superalloys in extreme thermal environments, though industrial adoption remains limited and the material is generally considered in the development or prototype stage for next-generation hypersonic and space applications.

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.
