Currently available superconductor substrates

At SUBRA we are proud to offer the most advanced superconductor substrate solutions currently on the market. We are upscaling production of our current products as well as constantly developing new and improved surface topologies to produce the most efficient superconductor systems. We produce special metal substrates for coated conductor tapes designed for ultra strong and high performance electromagnets, electrical transformers and power applications.

3D Multifilamentary Substrates

Our patented etching technnique creates a series of filaments across the surface of the tape, which help reduce energy losses and makes for a more efficient superconductor.

Customer Tailored Substrates​

Using our special patterning techniques we can develop unique substrate designs to match your specific needs and applications.​

Nanopolished Substrates​

SUBRA’s nanopolished tape is employed directly in commercial coated conductor production systems. Through our patented nanopolishing process, we are able to achieve an ultra smooth tape surface, free of defects and contaminants. The tape is Hastelloy based and is available in thicknesses between 30-100 µm.

3D Multifilamented Substrates​

3D multifilamentary-tape technology by SUBRA is based on a unique surface profile modification concept developed at the Department of Energy Conversion and Storage at the Technical University of Denmark (DTU). Filamentisation of the superconducting layer self-forms during deposition of the superconducting layer as our 3D profile effectively shades the lower parts of the tape. We first demonstarted MF-tape technology using commercial production systems in 2015. It has subsequently been advanced in collaboration with mulitple commercial HTS vendors. Superconducting stacks have for example been produced by pulsed laser deposition at Bruker HTS GmbH, and by metal organic chemical vapor deposition at SuperPower Inc. SUBRA's multifilamentary-tape can be employed directly in commercial coated conductor production systems.
