· JVASP-129385· NbRe

NbRe is a refractory metal alloy combining niobium and rhenium, designed to withstand extreme temperatures and harsh chemical environments where conventional superalloys reach their limits. This material is primarily explored for ultra-high-temperature aerospace applications, such as hypersonic vehicle components and advanced rocket engine nozzles, where its high melting point and oxidation resistance offer advantages over nickel-based superalloys; it remains largely in research and specialized aerospace use rather than widespread industrial production.

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.
