MF-tape : multifilamentary tape

This is our advanced NanoPolished 3D profile-substrate, which is utilized for direct production of filamentized superconductor tapes

Specifications

  • Standard filament widths: 0.3 – 2mm (for alternative widths optional short length pieces are now available, down to 25µm width)
  • Standard width: 4mm (12mm very soon available)
  • Standard thickness: 50-100µm (please contact us for alternative thickness)
  • Hastelloy-based (C276 or others including Ni-W is optional)
  • Final surface roughness: Ra~3nm
  • Tape length 1km (single tape capacity)

+SUBRAs MF-tape can be employed directly in commercial coated conductor production systems+
