Niobium Titanium Rod for Superconducting & Industrial Applications — High Purity, Custom Size

Baoji Huacan's niobium titanium rod is a high-performance Nb-Ti alloy product engineered for superconducting and industrial-grade applications. It consists of Nb-47wt%Ti or Nb-50wt%Ti and has superconducting critical temperature (Tc) of ~9.2 K and tensile strength of 450-900 MPa. It has a density of ~6.0 g/cm3, making it clearly heavier than steel and pure niobium. 10+ years of expertise in titanium machining, 40+ CNC machines, and an annual capacity of 1,000+ tons, every rod is manufactured under ISO 9001-certified quality control.

Exceptional Ductility: The Nb-Ti alloy rod may be co-reduced with copper matrices into thin multifilamentary wires without fracture, compared to brittle Nb3Sn.

High Strength to Weight Ratio: ~6.0 g/cm³ is much lighter than steel but yet has 450-900 MPa tensile strength.

Better Corrosion Resistance: Stable surface oxide layer resists oxidizing acids and chloride conditions.

Industry standard for cryogenic magnet systems. Superconducting Performance Tc ~ 9.2 K Hc2 > 15 T.

Composition Precision: Strict stoichiometry control ensures predictable pinning center distribution and consistent Jc values.

Our Precision Parts Processing Workshop

Titanium precision parts processing

Medical MRI Systems: The Nb-Ti rod is the core precursor for superconducting coils in 1.5T–3.0T MRI scanners. It enables stable, persistent magnetic fields essential for high-resolution diagnostic imaging in continuous cryogenic operation.

Particle Accelerators: Used in dipole and quadrupole magnets at facilities like the LHC, where performance under extreme radiation and superfluid helium cooling conditions is required.

NMR Spectrometers & Lab Magnets: Provides cost-effective, stable high-homogeneity fields for R&D environments, often used in outer coil sections alongside Nb₃Sn.

Aerospace & Industrial: The high strength-to-weight ratio and corrosion resistance make niobium titanium rod suitable for structural and chemical-process components in demanding environments.

Frequently asked Questions

Learn more about titanium grades, custom machining, lead times, and OEM solutions.

Q: What alloy ratio is best for MRI superconducting applications?

A：Nb-47wt%Ti is the industry standard. It provides the optimal balance of Hc2 and ductility needed for fine filament drawing.

Q: Can Nb-Ti rods be welded?

A：Yes. Welding requires an inert argon atmosphere or electron beam welding to prevent oxygen/nitrogen embrittlement that would degrade superconducting properties.

Q: How does Nb-Ti compare to Nb₃Sn?

A：Nb-Ti is ductile and can be drawn into wire before coil winding. Nb₃Sn handles higher fields but is brittle and requires a more complex wind-and-react process.

Q: What affects Critical Current Density (Jc)?

A：Jc is primarily determined by alpha-Ti pinning center precipitation during heat treatment and drawing. High homogeneity in the starting rod is essential for consistent results.
