Superconductors have the potential to power the future.
Our high-temperature superconductors are unlocking new technologies.
High-temperature superconductors have many exciting applications, many of which provide significant environmental benefits. They are a key enabler of energy generation through nuclear fusion and have the potential to improve the efficiency of wind turbines. Superconducting power cables facilitate greater energy transportation with significantly reduced physical footprints, enabling next-generation energy networks.
Superconducting “fault current limiters” enable the safe delivery of transient energy within these networks. The aviation and shipping industries are also utilising the high currents provided by superconductors to power electrical motors which can dramatically reduce CO2 emissions.
High-temperature superconductors are improving imaging technologies such as nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). They are expanding our knowledge of the physical universe through their use in particle accelerators and scientific instruments used in space.
Superconductivity is an immensely exciting technology that has garnered five Nobel Prizes in physics since its discovery in 1913 by Heike Kamerlingh Onnes.

Fujikura: advancing superconductors
We are a pioneer of the HTS production process.
Fujikura was instrumental in the development of second-generation superconductors. In 2020 Dr Yasuhiro Iijima, a Fellow in our Superconductor Research Department, received the IEEE’s Dr James Wong Award for outstanding technical contributions in the field of applied superconductivity where he developed the IBAD process which is widely used to produce high-quality REBCO based superconductors.
Mechanical performance
High fields generate high forces, so mechanical performance is extremely important for these materials. Our tapes show no degradation up to 400Mpa of compressive stress in the thickness direction, and 100MPa with the stress applied across the width. Our 50-micron substrate tapes can be used with bend radii of 5mm without degradation.
Variables
We have a range of widths for specific requirements. Wider tapes of 12mm tend to be used for applications where high fields or high currents are required. Our narrow tapes tend to be used for AC applications where AC losses need to be minimised.
We offer a range of copper coatings from 5 microns to 40 microns (on each side).
We provide non-copper insulation for applications where thermal losses need to be minimised.

[2] Non-Ap specification is mainly for conductors or other general use at relatively higher temperature.
[3] Artificial pinning specification is mainly for use in magnet applications at low temperature and high magnetic field.
[4] Ic@20K, 5T is a reference value and no guarantee of the actual performance.
[5] If requested, an option customising copper plating thickness is also available (e.g. 5µm, 10µm or 40µm).
