Product Overview
GR5 Titanium Medical Wire (Ti‑6Al‑4V, TC4) is an implant‑ready α+β titanium alloy wire engineered for high‑load medical device manufacturing. Produced at Baoji Yibait New Material's in‑house precision drawing workshop, this alloy balances high tensile strength, reliable fatigue performance and biological inertness, filling performance gaps left by pure titanium wire for load‑bearing implant scenarios.
Compliant with ASTM F136, ASTM F1472 and GB/T 13810 standards, our GR5 medical titanium wire undergoes strict impurity control for interstitial elements. It forms a stable self‑repairing passive oxide film under bodily fluid environments, restraining metal ion precipitation and lowering tissue irritation risks for both temporary and long‑term human implantation.
We deliver spool‑wound coiled wire and cut‑to‑length straight wire, with multiple surface finish options. Custom dimensional and surface requirements for medical OEM and R&D batches are fully supported.

Technical Advantages
Controlled interstitial purity for medical safety
Strict limits on oxygen, hydrogen, nitrogen and iron contents. Minimizes brittle risk and guarantees stable biocompatibility for implant component production.
01
Balanced strength‑to‑weight & anti‑fatigue performance
Higher strength than GR1/GR2 pure titanium wire, suitable for dynamic cyclic stress scenarios such as orthopedic cerclage and orthodontic ligation; resists repeated bending fracture during device processing and clinical service.
02
Superior corrosion resistance in physiological environment
Self‑generates protective TiO₂ passivation layer against chloride‑rich body fluids, excellent resistance to saline and tissue liquid corrosion, far outperforms conventional medical stainless steel.
03
High‑precision drawing & consistent surface quality
Multi‑pass cold drawing and segmented annealing process. Low surface defect rate, free of cracks, scales and scratches; good machinability for turning, stamping, bending and secondary forming of medical spare parts
04
Compatible with mainstream medical sterilization workflows
Stable performance under autoclave, EO gas and gamma‑ray sterilization, no surface degradation after repeated sterilization cycles.
05

FAQ
Q: What is the difference between GR5 medical titanium wire and GR23 (Ti 6Al 4V ELI)?
A: GR5 is standard Ti-6Al-4V alloy; GR23 (ELI version) adopts extra-low interstitial limits. For high-safety long-term implant projects, GR23 ELI is recommended. Our team can recommend suitable grade according to your end-use.
Q: Can you provide material test certificates for export medical projects?
A: Yes. Each lot is attached with MTR reports covering chemical composition and mechanical test data, matching ASTM F136 requirements.
Q: Do you accept custom-cut short-length straight wire?
A: Custom cutting service is available. Please offer target diameter, single-piece length, and quantity for a quotation.
Q: Is this wire ready for direct implantation?
A: Our GR5 titanium medical wire is raw base material for medical device manufacturing. Customers need to complete subsequent precision machining, cleaning and sterilization procedures before clinical usage.
