Substrate tape for Superconductors

Superconductors are revolutionizing modern energy technology. By reducing the temperature below a critical temperature, they lose their electrical resistance, enabling lossless current flow and extremely high magnetic fields.

Choosing the right substrate material is crucial for the production of high-temperature superconductors (HTS, HTSC), especially in the form of coated conductors.

This is where VDM® Alloy C-276 (also known as Hastelloy® C-276 or material 2.4819) sets the industry standard:

Substrate for HTS tapes: VDM® Alloy C-276 serves as a robust substrate tape for superconducting REBCO layers such as YBCO.
Thermal stability: The alloy retains its excellent mechanical properties even at cryogenic temperatures close to absolute zero.
Corrosion resistance: Thanks to its high molybdenum and chromium content, it offers high protection against aggressive media.
Precision: Its excellent workability allows the production of ultra-thin, flexible substrate tapes for compact magnetic coils and power transmission lines.
Applications: Superconducting magnets, fusion reactors, MRI systems, highly efficient power transmission lines, energy storage, particle accelerators, Superconducting Fault Current Limiter, Superconducting electric machine

About VDM® Alloy C-267

VDM® Alloy C-276 is a nickel-chromium-molybdenum alloy containing tungsten.
VDM® Alloy C-276 (2.4819/N10276) is resistant to both oxidizing and reducing media in a wide range of chemical processes. Due to its high chromium and molybdenum content, this alloy is extremely resistant to attack by chloride ions. This resistance is further maximized by the addition of tungsten.
This material therefore finds a wide range of applications in the chemical and petrochemical industries, for components in organic processes containing chlorides, as well as for catalysts. VDM® Alloy C-276 is particularly suitable when hot, contaminated mineral acids, solutions, or organic acids (such as formic and acetic acid) as well as seawater are present.
