As the operating temperatures and the maximum achievable critical currents are highly sensitive to the microstructure of the superconducting film, the manufacturing technique and conditions used are of paramount importance. Fujikura's 2G HTS wires are manufactured using our advanced Ion Beam Assisted Deposition (IBAD) and Hot-wall Pulsed-Laser Deposition (PLD) techniques which we have perfected over the course of more than 20 years - allowing the production of longer lengths of high-quality tapes with greater critical current densities and at shorter processing times.

Fujikura's Yttrium-based superconducting wires possess superior characteristics over Bismuth-based superconductors under an applied magnetic field allowing it to retain its superconductive properties under real-world operating conditions. On the other hand, our 2G HTS tapes have demonstrated the ability to generate remarkably high magnetic flux densities and critical currents at wide operating temperatures.  Combined with highly robust mechanical properties, Fujikura's 2G HTS wires are ideal for a wide range of industrial and scientific applications today.

Especially for electrical Motors and Generators, a superconducting electromagnetic core is able to provide a tremendous improvement in efficiency over conventional copper windings as there are virtually no heating losses; this allows for massive reductions in size and weight of the component which further surmounts to a significant amount of savings in the long term.

As the technical capabilities of 2G HTS tapes have  progressively improved, the greater magnetic flux densities produced, compact tape-shape and longer lengths of the HTS wires appear to be a more attractive option for applications requiring the generation of strong electro-magnetic fluxes. Magnetic Resonance Imaging (MRI) Scanners, Nuclear Magnetic Resonance (NMR) Spectrometers and Magnetic Levitation (Maglev) transport which conventionally depend on heavy, metallic Low Temperature Superconductors (LTS) could achieve greater performance and economic efficiency by utilising 2G HTS instead.

Since the discovery of High Temperature Superconductivity more than 20 years ago, Fujikura has been at the forefront of its research and development with the aim of implementing commercially-viable Superconductivity for real world applications. From being the first to fabricate 100m long HTS wires  in 2004 to the curent production lengths of 800m and above, Fujikura has been setting records as testaments to our technical progress and dedication to the field of Superconductivity. Fujikura is now capable of routinely manufacturing wires with critical current densities greater than 3,000,000 A/cm² and production rates of 10-100m/h - a phenomenal leap in progress from 500,000 A/cm² at 10cm/h in the 1990s. Until today, we are still pushing the boundaries as demonstrated by our current world record production Ic × L value of 466,981 A/cm.

In order to meet our clients' specific requirements, the production of 2G HTS wires is highly customised to individual orders by our advanced manufacturing facilities in Japan; various aspects including width, substrate layer thickness, shunt layer can be accommodated depending on the application.
