What Is Ti-6Al-7Nb Wire?
Ti-6Al-7Nb wire is a wrought titanium alloy product (UNS R56700, ASTM F1295) supplied in small diameters for applications where bar stock is not practical - such as surgical implant components, orthopedic fixation parts, and precision medical devices requiring tight dimensional control.
Compared with Ti-6Al-7Nb bar, wire is the preferred form for applications involving coiling, automated feeding, spring/fastener components, or fine-diameter implant parts that cannot be machined economically from bar stock. TSM Technology can discuss diameter, supply form, surface condition, certification, and other technical requirements based on individual project specifications.

Ti-6Al-7Nb Wire Applications
Ti-6Al-7Nb wire is used where small diameter, controlled material properties, strength, corrosion resistance, and dimensional accuracy are required.
Medical & Orthopedic Applications
Suitable for selected surgical implant, orthopedic, and precision medical components where small-diameter titanium alloy material is required.
ASTM F1295 covers wrought Ti-6Al-7Nb alloy products used in the manufacture of surgical implants.
Precision & Research Applications
Suitable for precision components, prototypes, research projects, and material development where controlled wire dimensions and consistent alloy properties are required.
Industrial Applications
Suitable for selected industrial components requiring a lightweight titanium alloy with high strength and corrosion resistance in wire form.
For medical applications, final material selection should be based on the applicable product specification, device design, manufacturing process, validation, and regulatory requirements.
Manufacturing Process for Ti-6Al-7Nb Wire
Ti-6Al-7Nb wire is manufactured through controlled hot working and cold working to achieve the required diameter, dimensional tolerance, surface condition, and mechanical properties.
Hot Working
Hot working is used for the initial reduction and forming of Ti-6Al-7Nb material. Processing parameters are controlled according to the material condition and target wire size.
Cold Working
Cold working or cold drawing is used for further diameter reduction and dimensional control. Multiple working passes may be applied for smaller wire sizes, with intermediate heat treatment when required to maintain ductility and processing stability.
Heat Treatment
Annealing may be applied between or after working stages according to the required material condition and mechanical properties. The specific temperature and holding time are controlled according to the production specification.
Surface Finishing
The finished wire is available with bright or pickled surfaces. Final sizing, straightening, coiling, spooling, or cut-to-length processing can be provided according to customer requirements.
Quality Control
TSM Technology supports material traceability from raw material to finished product. Depending on the order requirements, Ti-6Al-7Nb wire can be supplied with:
- MTC acc. EN 10204 3.1
- Chemical composition and mechanical test records
- Dimensional and surface inspection
- Heat / lot traceability
- Third-party inspection where required
Additional inspection or documentation requirements should be specified before quotation.
Ti-6Al-7Nb Wire vs. Ti-6Al-7Nb Bar
TSM Technology supplies both Ti-6Al-7Nb wire and bar. Although both products use the same alloy designation and ASTM F1295 standard, their dimensions, supply forms and downstream applications are different.
