· JVASP-130171· Er3Nb

Er3Nb is an intermetallic compound composed of erbium and niobium, belonging to the rare-earth transition-metal family of materials. This compound is primarily of research interest for high-temperature structural applications and advanced functional materials, where the combination of rare-earth and refractory metal properties may offer improved creep resistance, oxidation stability, or specialized magnetic/electronic characteristics compared to conventional superalloys.

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.
