Niobium Titanium Alloy Wire: Nb52-Ti48, Nb50%-Ti50% and Nb45%-Ti55%, 0.1–4 mm, Annealed

A conductor has to be workable while you wind it. That is what superconducting magnet winding demands. Niobium Titanium Alloy Wire comes from Shaanxi Chuanghui Daye Metal Material Co., Ltd., and it arrives annealed. You can pick from three grades: Nb52-Ti48, Nb50%-Ti50%, and Nb45%-Ti55%. Sizes run from 0.1 mm to 4 mm. Want a cut length? You get that exact length. After annealing the alloy stays ductile. That makes drawing easier. Winding and forming get easier too. On this page you will find typical NbTi properties and the supply range. Handling notes are here as well. Send a quote request and you will also see the details we need from you.

Why NbTi Is Used in Superconducting Magnets

NbTi means niobium titanium. This Type II superconductor works at low temperatures. Magnet builders depend on it heavily. It reaches them for conductor making and winding as this product.

Below its transition temperature, NbTi carries current with zero electrical resistance. A magnet made from this material holds a strong field. That field also stays steady. A copper winding gives off resistive heating all the time, and here you get none of it. Large cryogenic systems can therefore run at lower cost.

You will see Nb-47wt.%Ti and Nb-50wt.%Ti more than any other NbTi composition. Once the conductor is finished, the alloy usually sits inside a matrix of high-purity copper or copper-nickel.

General NbTi Reference Properties

The values below are general figures for NbTi alloys. They are not guaranteed specifications of this wire.

Critical temperature (Tc): about 9.2 K
At 0 K the upper critical field (Hc2) is about 14.5 T
Cool the sample to 4.2 K and Hc2 lands near 11 T
Magnetic field generated in magnet use: up to 10 T

Nb3Sn is brittle. NbTi is not. Bend it, draw it, and no cracks show up. The copper stabilizers go through the same drawing pass. A multifilamentary conductor is the result. Thousands of filaments sit inside it, each only a few microns across. The copper matrix does two jobs in these wires. Thermal stability comes from a high residual resistance ratio (RRR). That same copper also provides quench protection. We also supply the Niobium Titanium Alloy Wire in custom sizes to suit your drawing.

Grades and Composition Control

Titanium content is shown right in the grade name. That share can be anywhere from 45% to 55%. If you need something close to the standard Nb-47Ti mix, look at Nb52-Ti48. Nb50%-Ti50% is the match for the common Nb-50Ti. Want a higher titanium share? You can have it. In that case, choose Nb45%-Ti55%.

Two interstitial elements count here: oxygen and carbon. Both call for tight control. Let too much of either into the filament and it may snap during drawing. Heat treatment is standard industry practice as well. This step precipitates alpha-titanium flux-pinning centers. Thanks to those centers, critical current density (Jc) rises in magnetic fields.

Annealed Condition and Processing

Annealed this product is soft. It is easy to work. Your drawing step starts from a ductile base. Your winding and forming steps also start from that ductile base.

Fine-filament jobs and heavier conductor stock both work with diameters of 0.1 mm to 4 mm. We cut each length to your request. That way, you get the size your process needs.

Applications of Niobium Titanium Alloy Wire

Magnet projects use Niobium Titanium Alloy Wire as a starting material. Winding and multifilamentary conductor builds both begin with it. NbTi shows up widely in superconducting magnets and MRI systems. Large cryogenic systems rely on it too, to hold high fields at lower running cost.

Welding and Handling

Niobium oxidizes quickly once it meets air and gets hot. Ordinary lead-tin solder won't stick to it. So most shops go with TIG welding instead. That work happens inside an argon chamber, where the control is tight. Another route people take is electron beam (EB) welding. Before production, check joining and surface requirements against your own process.

FAQ

Q: Which grades are available?

A: Nb52-Ti48, Nb50%-Ti50%, Nb45%-Ti55%.

Q: What sizes and lengths do you offer, and in what condition does the material arrive?

A: Diameters run from 0.1 mm to 4 mm. Any length you need is fine. The wire is annealed.

Q: So why is the annealed condition such a big deal?

A: The alloy is still soft once annealing is done. It stays ductile too. Drawing gets simpler because of that. The same holds for winding. Forming gives you less trouble as well.

Q: Does standard soldering work on this wire?

A: No. Niobium oxidizes quickly once it sits in air and gets hot. Ordinary lead-tin solder won't stick to it. Most shops go with TIG welding inside an argon chamber they can control. EB welding shows up a lot too.

Q: What details should go into a quote request?

A: Tell us the grade. Add the diameter and length. We also need the end use. Put down the quantity too. If a surface, matrix, or RRR requirement applies, include it.
