· JVASP-39191· ScNb

ScNb is an intermetallic compound composed of scandium and niobium, belonging to the refractory metal alloy family. This material is primarily of research and development interest rather than established commercial production, with potential applications in high-temperature structural applications where its combination of low density and refractory properties could offer advantages over conventional superalloys. Engineers would consider ScNb in specialized aerospace and space propulsion contexts where extreme temperature resistance and lightweight performance are critical, though material availability, processing difficulty, and limited production infrastructure currently restrict its use to laboratory and prototype development.

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.
