· JVASP-142404· NbVCo

NbVCo is a refractory high-entropy alloy (HEA) composed of niobium, vanadium, and cobalt. This experimental material belongs to the multi-principal-element alloy family, designed to leverage the combined properties of its constituent elements—particularly the high-temperature strength of refractory metals and the ductility contributions of transition metals. Research into NbVCo-family alloys targets extreme-environment applications where conventional superalloys reach their thermal limits, though this specific composition remains primarily in development rather than established 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.
