JASTEC

What JASTEC does

JASTEC (Japan Superconductor Technology, Inc.) is a Japanese manufacturer of superconducting wires and magnets, organized as a wholly-owned subsidiary of JEOL Ltd. and operating from Kobe with production in Kitakyushu and a sales office in Tokyo. The company was formed in 2002 through the merger of Japan Magnet Technology's magnet business and Kobe Steel's superconducting wire business, with R&D roots extending to 1964 at Kobe Steel's Asada Research Laboratory. Its product portfolio spans four families: cryogen-free superconducting magnets (eliminating liquid helium via GM-cryocooler conductive cooling, up to 15T), high-field research magnets up to 20 Tesla, NbTi and Nb3Sn superconducting wires (including ITER-qualified grades), and NMR superconducting magnets (400-600 MHz JMTC series plus world-record 920/930 MHz systems).

The company sells exclusively through direct B2B enterprise sales — no third-party distributors — to four horizontal customer segments: research and academic institutions (MIT, Tsinghua University, NIMS, RIKEN, QST, KERI), scientific instrument manufacturers (Bruker Biospin, JEOL, Thermo Fisher Scientific), medical equipment OEMs (GE Healthcare for MRI), and fusion energy projects (ITER). Pricing is not publicly disclosed; deals are negotiated per inquiry and supported by installation/setup services and consulting for superconducting and cryogenic technology.

JASTEC's competitive position rests on more than 60 years of accumulated superconducting know-how, validated by world-record achievements (920 MHz and 930 MHz NMR magnets, 24.0 Tesla magnetic field in 2011 with NIMS), a 1,000+ cumulative NMR magnet delivery track record, ISO9001:2015 and ISO13485:2016 quality certifications, and a small global supplier base that creates high qualification barriers. Its product pages explicitly note that published specifications are for reference only and do not imply guarantee, consistent with a custom-engineered, technical-sale business model rather than catalog sales.
