· JVASP-108818· NbSN

NbSn (niobium-tin) is an intermetallic compound and superconductor that forms the basis of practical superconducting wire and magnet technology. It is widely used in high-field superconducting magnets for MRI systems, particle accelerators, fusion reactors, and research electromagnets, where its ability to conduct electricity without resistance at cryogenic temperatures enables exceptionally strong magnetic fields that would be impractical with conventional conductors.

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.
