We specialize in precision Hastelloy® HPM® C276 Strip—a heat-resisting alloy foil trusted for its performance in demanding superconducting environments.
This metal foil substrate is the industry standard for High-Temperature Superconducting tapes, enabling superconductivity across broader temperature and magnetic field ranges.
Why Hastelloy® HPM® C276 Strip Alloy Foil for Superconductors?
Superconducting cables require ultra-smooth, high-purity substrate material to support thin-film deposition. Our Hastelloy® HPM® C276 Strip (UNS N10276) foil meets these exacting standards with:
- Ultra-Smooth Surface Finish
Ultra smooth surfaces with roughness less than 2 micro-inch Ra, ideal for thin-film coatings such as MOCVD (Metal Organic Chemical Vapour Deposition) and IBAD (Ion Beam Assisted Deposition).
- Tight Thickness Tolerances
Precision cold-rolling delivers thicknesses tolerances of ±0.00005", ensuring uniform current distribution in HTS tapes.
- Mechanical Customization
Capability to temper the foil substrate to meet specific mechanical properties.

What Is Substrate Material for Superconductors?
In superconducting applications, substrate materials form the essential base layer onto which superconducting films are deposited. Superconducting films are extremely thin and sensitive to imperfections. The substrate must therefore provide:
- Dimensional stability to prevent warping under thermal cycling
- Electrical neutrality to avoid interference with superconducting currents
- Mechanical strength to support handling and integration
- Surface smoothness to ensure uniform film deposition and adhesion
For High-Temperature Superconductor (HTS) tape products,
Hastelloy® HPM® C276 Strip is widely used due to its ability to maintain superconductivity across a broad range of temperatures and magnetic fields. It supports higher critical current densities and remains stable under demanding conditions.
