In the race to unlock the full potential of superconducting technologies, the choice of substrate material is critical.
At Hamilton Precision Metals, we’ve positioned ourselves at the forefront of this innovation with our precision-engineered HPM® C-276 strip and foil - a heat-resistant alloy that’s critical to high-performance superconducting systems.
As the industry standard for High-Temperature Superconducting (HTS) tapes, our substrate foil enables superconductivity across wider temperature ranges and magnetic fields, pushing the boundaries of what’s possible in energy, healthcare, transportation, and computing.
The Science Behind the Surface
Superconducting cables demand more than just conductivity - they require a substrate that’s ultra-smooth, dimensionally stable, and mechanically robust. Our
HPM® C-276 foil delivers on all fronts.
Its surface finish, with roughness less than 2 micro-inch Ra, is ideal for thin-film deposition techniques, ensuring optimal performance. Precision cold-rolling achieves thickness tolerances within ±0.00005", a level of accuracy that supports uniform current distribution - essential for HTS tape functionality. And with the ability to temper the foil to meet specific mechanical requirements, we offer customization that meets the demands of cutting-edge applications.
What Makes a High Performing Substrate?
Superconducting films are incredibly thin and sensitive to imperfections. The substrate must offer dimensional stability to withstand thermal cycling, electrical neutrality to avoid interference, mechanical strength for integration, and surface smoothness for consistent film adhesion. HPM® C-276 foil meets all these criteria, making it the preferred choice for HTS tape products.
Enabling the Future of Technologies
From powering AI data centers to enabling magnetic levitation trains, our foil substrate is already making an impact across industries.
In energy transmission, it supports superconducting cables that deliver power with minimal loss—an essential feature for fusion energy systems and next-gen infrastructure such as data centers. In medical imaging, it underpins the high-field magnets used in MRI and NMR systems, improving diagnostic precision.
The world of quantum computing also benefits from our substrate foil, providing the foundation for thin-film superconductors that drive breakthroughs in processing speed and sensing accuracy.
As 5G networks expand, our foil is emerging as a key material for high-frequency, low-loss transmission systems, helping to meet the growing demand for faster, more efficient connectivity.
Even in transportation, the impact is tangible. Magnetic levitation trains rely on superconducting systems supported by our substrate—bringing futuristic travel closer to reality.
