Implant Grade Titanium Wire

Ti-6Al-4V ELI High-Toughness Medical Titanium Alloy Wire ASTM F136 orthopedic implant-grade titanium wire (Ti-6Al-4V ELI) is our core product specifically designed for minimally invasive orthopedic implants and skeletal fixation scenarios. Strictly adhering to the ASTM F136 international medical standard, it belongs to the low-interstitial-element implant-grade titanium alloy material, which differs from ordinary medical-grade pure titanium wire. With ultra-high specific strength, excellent osseointegration capability, and fatigue resistance, it is the preferred material for orthopedic trauma repair, spinal fixation, and micro fixation in hand and foot surgery.

As a source manufacturer rooted in China's Titanium Valley and certified with ISO 13485, we focus on the core needs of orthopedic implant scenarios. With "orthopedic exclusive customization + medical-grade clean production + full-process compliance assurance + orthopedic specialized after-sales service" as our core strengths, we address industry pain points such as "insufficient strength, susceptibility to fracture, and poor osseointegration" in orthopedic titanium wire. We provide highly adaptable, safe, and stable orthopedic implant-grade titanium wire solutions for global orthopedic device manufacturers and hospital supporting institutions. All products come with complete MTR test reports and traceability documents, enabling direct use in orthopedic implant device production.

ASTM F136 Titanium Wire for Orthopedic Implants Core Grade Characteristics

ASTM F136 (Ti-6Al-4V ELI) serves as a benchmark grade in the field of orthopedic implants, with its core advantages precisely meeting the stringent requirements of orthopedic implant scenarios, presenting significant differences compared to standard medical-grade pure titanium (ASTM F67 Gr1/Gr2). This grade achieves reduced material brittleness and enhanced mechanical properties and biocompatibility through strict control of interstitial elements such as oxygen, nitrogen, and carbon.

ASTM F136 Orthopedic Implant Titanium Wire Specification & Application Table

Summarized in three points:

1. Superior Mechanical Performance: Tensile strength of 860 MPa or more, a yield strength of 795 MPa or more, and 10% or more elongation, and it keeps good toughness even at a thickness of 1.0-3.0mm commonly used for orthopedics. So it is able to bear the micro-motion loads which occur during bone healing, and this makes it hatitious for post-implant issues such as wire breakage or deformation, thus it is the one which can resolve the challenges, that standard titanium wires are prone to failure in weight bearing orthopedic application.

2. Highly osseointegrable: It has no cytotoxicity or sensitization as assessed according to entire ISO10993 biocompatibility standards. The oxide film formed on the surface is dense and Bone tissue bonding rate with titanium wire is rapidly increased, which can decrease the rejection reaction of after implantation and the healing process of patient.

3. Very good corrosion resistance: It provides a good corrosion resistance in human body fluid, blood and related orthopaedic post-operative sterilization solutions. It is not anticipated that the material will degrade or that toxic substances will be released during long term implantation. It has a decades long service life and fully satisfies the requirements of long term orthopaedic implants. Using precision making process specialized for orthopedic processing, we can provide wire diameter tolerances, and surface electropolishing treatment (Ra≤0.2μm) to be used in orthopedic implant component manufacture directly without being subjected to any secondary processing. Furthermore, adopting advanced vacuum smelting technology, the purity of the product is more than 99.95% and the impurity content is less than 10ppm, so the biocompatibility and mechanical stability are further enhanced.

1. Hand and Foot Micro-Fixation Application: for fixation of small bone fractures and joint repairs in hand and foot. Made of ASTM F136 Titanium wire with size 0.5mm–1.0mm, tolerance of ±0.005mm, surface is electropolished (Ra≤0.15μm). It provides very good toughness and strength, just satisfying the fixation need to tiny bones without sacrificing surrounding soft tissues. In addition, the promoted osseointegration stimulates bone regeneration and reduces postoperative complications.A multi-pass drawing processing may be used to prepare the titanium wire of this specification, which resolves the problem of elastic deformation in processing of titanium alloy and the dimensional accuracy and surface quality can be guaranteed.

2. Scenario of Orthopedic Trauma Repair: Fractures of the limbs and pelvis. The tensile strength is consistently above 860MPa and the product comes in 1.0mm – 2.0mm diameter with ±0.01mm tolerance. It can withstand micro-movement loads during the bone healing period, resist postoperative disinfection medium corrosion, and supports customized cutting lengths (0.5m–1000m/roll). It directly adapts to automated assembly of orthopedic instruments, eliminating the need for customer re-cutting. Through the improvement of annealing process, we enhance the fatigue resistance of the titanium wire and the fatigue life test result meets 120% of the industry standard, achieving the effect of prohibiting material fatigue failure after long-term use in vivo.

3. spinal fixation example , used for spinal fusion and intervertebral disc repair. Material is 2.0mm–3.0mm, with tolerance of ±0.01mm Excellent fatigue resistance and stability. It conforms to the physiological curvature of the spine, reducing post-implantation impact on spinal mobility. Its excellent biocompatibility does not induce rejection reaction to fulfill long-term implantation. This specification is undergoing stringent osseointegration test, with less than 0.1% rejection after implantation, which meets the standard of advanced orthopedic implant.

We are one of the few original manufacturers in the industry capable of stable mass production of ASTM F136 titanium wire specifically for orthopedic applications. With 12 years of dedicated R&D and production in orthopedic implant titanium wire, we possess specialized manufacturing and customization capabilities tailored to orthopedic scenarios, distinct from the "general-purpose production model" of ordinary titanium wire manufacturers. Equipped with imported precision cold-drawing machines, constant-temperature annealing furnaces, and laser diameter calibrators, we employ a multi-pass progressive drawing process.

Combined with orthopedic-specific medical molds, this ensures uniform dimensional accuracy and surface quality across every wire, eliminating impurities from mold wear. The entire production process takes place in a Class 100,000 cleanroom, featuring closed-loop control from raw material processing to wire drawing, annealing, and finished packaging-preventing contamination from dust and impurities. Each batch undergoes particle content testing and orthopedic-specific mechanical performance evaluations, fully complying with implant-grade medical standards to guarantee product safety at the production source.
