· JVASP-90127· NbReSi

NbReSi is a refractory metal intermetallic compound combining niobium, rhenium, and silicon, designed for extreme-temperature structural applications. This material belongs to the family of high-temperature intermetallics and is primarily of research and specialized industrial interest, where its combination of refractory elements offers potential for maintaining strength and oxidation resistance in environments where conventional superalloys approach their limits. Its application space centers on aerospace propulsion, power generation, and other sectors demanding materials that perform at very high temperatures with minimal creep.

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.
