PmNb
metal· JVASP-129378· PmNb
PmNb is a refractory metal alloy based on niobium with promethium additions, belonging to the family of high-temperature transition metal systems. This material is primarily of research and specialized interest rather than established production use, developed to explore enhanced creep resistance and oxidation performance at elevated temperatures characteristic of niobium-based compounds.

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.
