Key Players
Competitive Landscape
Competition in the trapped field magnets sector spans top-seeded melt-growth crystal foundries, second-generation REBCO tape manufacturers, and cryogenic magnet system integrators. Crystal growth specialists including Nippon Steel Corporation and CAN SUPERCONDUCTORS, s.r.o. alongside Adelwitz Technologiezentrum GmbH (ATZ) and Evico GmbH produce single-domain GdBCO and YBCO pucks reinforced with shrink-fit stainless-steel bands. Coated-conductor producers led by Faraday Factory Japan LLC and Furukawa Electric Co., Ltd. (SuperPower Inc.) supply high-engineering-current-density REBCO tapes that are laser-slit and stacked into composite trapped-flux annuli. At the system tier, Tokamak Energy Ltd. and ASG Superconductors S.p.A. integrate bulk and stacked-tape pucks with conduction-cooled cryocoolers and pulsed magnetization coils. Aerospace and NMR buyers qualify vendors on trapped surface Tesla uniformity and thermal-cycle fracture resistance.
Single-grain bulk and upstream 2G HTS tape scaling: Adelwitz Technologiezentrum GmbH (ATZ) scaled seeded single-grain YBCO and GdBCO bulk production capable of trapping 17 Tesla at 20 to 30 Kelvin, while Faraday Factory Japan LLC unveiled its MIRAI HTS tape (1,000 A/mm2 at 20 K and 20 T) in June 2025 as upstream feedstock for stacked-tape annuli and Tokamak Energy Ltd. validated REBCO tape durability under 150-megapascal compressive loads in September 2026. Melt-textured REBCO crystal foundry expansion: CAN SUPERCONDUCTORS, s.r.o. relocated to expanded Czech production premises in April 2026 to scale single-grain REBCO bulk output before exhibiting at ASC 2026 in September 2026 [19]. Cryogen-free multi-Tesla spectrometer and energy integration: ASG Superconductors S.p.A. and INFN unveiled a 5-plus-Tesla, 1-megajoule REBCO magnet at ASC 2026 in Pittsburgh while launching the EUR 5.8 million SURE MgB2 data-center power project in July 2026.

Industry R&D and capital investment are converging on fracture-tough stacked REBCO tape annuli and silver-doped single-grain GdBCO pucks operated between 20 and 50 Kelvin. Suppliers that deliver pre-banded trapped-field cartridges paired with calibrated multi-pulse PFM charging protocols are projected to secure long-term positions on electric aircraft and compact NMR platforms.
How are key market participants positioned in the trapped field magnets market?
Nippon Steel Corporation and CAN SUPERCONDUCTORS, s.r.o. alongside Adelwitz Technologiezentrum GmbH (ATZ) and Evico GmbH position themselves as specialized crystal foundries supplying single-grain GdBCO and YBCO bulk discs and levitation modules. Faraday Factory Japan LLC and Furukawa Electric Co., Ltd. (SuperPower Inc.) serve as upstream coated-conductor tape manufacturers supplying 2G REBCO tapes for stacked-annulus magnets. Tokamak Energy Ltd. and ASG Superconductors S.p.A. operate as full-system magnet integrators building cryocooled HTS and MgB2 assemblies.
What qualification or purchasing requirements matter most to prospective buyers?
Aerospace and naval propulsion engineers require verified trapped surface flux density above 5 Tesla at 30 Kelvin with zero mechanical cracking across 1,000 thermal and pulsed-magnetization cycles. Benchtop NMR and portable MRI manufacturers demand spatial field homogeneity better than 10 parts per million across the sample bore and flux creep decay below 1% per decade. Buyers also mandate vacuum-impregnated stainless-steel or carbon-fiber compression collars.
Which product or application capabilities distinguish the leading companies?
Nippon Steel Corporation leads in large-diameter QMG single-grain GdBCO monoliths with uniform rare-earth-211 precipitate dispersion. CAN SUPERCONDUCTORS alongside ATZ GmbH excels in melt-textured bulk rings trapping up to 17 Tesla at 20 to 30 Kelvin.

Research Methodology
The trapped field magnets market assessment was conducted using a combination of primary research, secondary research, and superconducting foundry capacity triangulation. Secondary research included analysis of Applied Superconductivity Conference (ASC) and MT29 technical proceedings, CERN and ITER superconducting magnet test records, U.S. Department of Energy and METI Japan superconducting disclosures, and verified corporate press releases. Primary interviews were undertaken with top-seeded melt-growth crystal foundry directors, 2G REBCO coated-conductor tape engineers, superconducting aviation motor designers, and benchtop NMR spectrometer manufacturers to validate puck pricing, trapped Tesla ratings, and pulsed-field magnetization yields. Market estimates and projections from 2026 to 2036 were cross-checked against commercial melt-growth furnace throughput, kilometer-scale HTS tape output, and naval and aerospace propulsion demonstrator budgets.
