Product Overview
ASTM F67 pure titanium wire is unalloyed commercially pure titanium material formulated specifically for surgical implant and medical device manufacturing. Manufactured at YIBAITE's Baoji titanium processing facility, our Gr1, Gr2, Gr3, Gr4 titanium wire strictly follows ASTM F67 chemical and mechanical limits, with strict control over interstitial elements including oxygen, iron, carbon, nitrogen and hydrogen to guarantee stable biocompatibility and corrosion resistance inside physiological environment.
Different from ordinary industrial-grade CP titanium wire, our ASTM F67 titanium wire undergoes dedicated medical-oriented drawing, intermediate annealing, and surface cleaning workflow. Each production lot carries complete material traceability documents, supporting device manufacturers for qualification audit and regulatory filing. We deliver wire in spool-wound coil or precision straight-cut segments, covering ultra-fine thin wire up to medium-diameter round wire for diverse medical component forming.
Key Features
Implant-grade purity: Rigid control of interstitial impurities, match ASTM F67 UNS R50250 / R50400 / R50550 / R50700 requirement.
Tunable ductility & strength: Gr1 for maximum formability; Gr2 as general-purpose grade; Gr3-Gr4 for higher tensile demand
Excellent cold workability: Suitable for coiling, bending, stamping, staples forming without material cracking
Smooth low-defect surface: Minimize particle residue, adapt to autoclave, gamma-ray sterilization cycles
Superior body-fluid corrosion resistance: Stable native TiO₂ passivation layer resists human fluid erosion, lower risk of tissue reaction
Batch-to-batch repeatability: Consistent dimension, mechanical property and surface status across serial production
Complete documentation support: MTC / EN10204-3.1 test report, heat-lot traceability available for every shipment

Technical & Processing Advantages
In-house full-chain production in Baoji
From titanium sponge raw material inspection → multi-pass cold drawing → precise intermediate annealing → surface purification → non-destructive inspection → final spool winding. We do not outsource core drawing procedures, so every process node can be tracked and adjusted according to medical-grade requirement.
01
Strict interstitials monitoring
We track oxygen, iron content for every heat number, avoid material drifting close to standard upper limits which may cause unstable ductility in post-processing.
02
Specialized winding technology for fine wire
Ultra-fine titanium wire is wound with controlled tension to eliminate knot, scratch and deformation, guarantee smooth automatic feeding for customer stamping equipment.
03
Multi-item inspection before delivery
Dimension check, mechanical tensile-elongation test, surface visual inspection, chemical composition verification. Non-destructive testing option can be arranged for high-risk implant projects.
04
Flexible custom capability
Adjust straight-cut length, spool size, surface treatment according to customer drawing; support pre-production sample validation before mass order.
05
Our Factory Strength (Baoji Yibaite)
Baoji Yibaite is rooted in Baoji, China's core titanium industrial cluster. We focus on medical-grade titanium semi-finished materials for global medical device manufacturers. Our workshop runs dedicated production zones for implant-grade titanium products, separating medical-grade production from general industrial titanium processing to prevent cross-contamination.
We accumulate rich experience supplying ASTM F67 titanium wire for medical component factories overseas. Our technical team can assist customers on grade selection, parameter matching and material document requirements. We support quick sample turnaround and stable serial bulk supply.
Typical Applications
Surgical staples, titanium ligation clips
Medical suture wire, orthopedic fixing small components
Dental orthodontic accessories, dental implant auxiliary parts
Minimally-invasive surgical instrument core parts
Biocompatible precision spring, forming medical hardware
