Key Material Properties and Technical Specifications

The product represents the purest commercially available titanium grade for medical use. Its low interstitial content provides exceptional formability and weldability.

This material exhibits outstanding resistance to body fluid corrosion. The natural titanium oxide layer forms instantaneously upon exposure to air, creating a protective barrier that prevents ion migration into surrounding tissue.

The grade's superior ductility makes it ideal for cold-forming operations. Medical device manufacturers benefit from easier fabrication processes without compromising structural integrity.

Clinical Applications and Medical Device Uses

This product is used in a variety of surgical and therapeutic procedures. Its good biocompatibility avoids harmful tissue reactivity in long-term implantation.

Orthopaedic surgeons use the material in bone fixation plates and screws. The small weight reduces the load of the patient and provides enough mechanical support for fracture healing.

Dental experts choose titanium GR1 for the manufacturing of implant abutments and framework. The material has osseointegration properties, i.e. it may attach directly to the bone without creation of an intermediate fibrous tissue layer.

Manufacturers of cardiovascular devices use this grade for pacemaker casings and vascular clips. Its non-magnetic qualities assure full MRI compatibility, enabling patients to undergo diagnostic imaging without safety issues or artefact interference.

Reconstruction of the maxillofacial region is performed with custom-made mesh and plates from GR1 bars. The material has great formability which facilitates accurate anatomical contouring intra-operatively.

Manufacturing Excellence and Quality Assurance

We use precise machining and precision die forging to convert titanium bars into finished medical components. Quality is checked continuously at all stages of processing during the production process.

The chemical composition is verified by analytical procedures of ASTM E1409 and E1447. We do batch specific testing to confirm the interstitial element concentrations are within specification limits.

Mechanical testing is conducted in accordance with ASTM E8 tensile and ASTM E290 bend testing requirements. Destructive testing is conducted on each production batch to verify strength, ductility and fatigue resistance criteria.

Ultrasonic inspection (per AMS 2631) for internal discontinuities. This non-destructive evaluation confirms volumetric soundness which is crucial to sterile barrier maintenance of implanted devices.

Surface quality examination Check centerless ground or peeling finishes to Ra values less than 0.8µm. The surface preparation removes the alpha case layer and offers the best conditions for the following CNC machining processes.

Comparative Advantages Over Alternative Materials

The product has various advantages over stainless steel surgical materials. A density of 4.5 g/cm3 compared to 8.0 g/cm3 of stainless steel reduces implant weight by around 44%.

It is more corrosion resistant than 316L stainless steel or cobalt chromium alloys. The passive oxide layer is stable for physiological pH ranges and chloride concentrations of bodily fluids.

Biocompatibility testing shows no harmful effects in ISO 10993 testing. GR1 titanium removes the metal sensitivity problems of nickel-containing alloys that impact around 10-15% of patient populations.

Ti-6Al-4V alloys ASTM F136 have a stronger strength, however GR1 is better ductile for forming operations. In cold working procedures manufacturers can achieve tighter bend radii without initiating a crack.

The material’s thermal expansion coefficient is also quite close to that of human bone. Such compatibility reduces the stress concentration at the bone-implant interface during temperature variation.

Customization Capabilities and Processing Services

Baoji INT Medical Titanium provides comprehensive customization for ASTM F67 GR1 Medical Titanium Bar specifications. We manufacture diameter ranges from 6mm to 300mm with length tolerances held to ±0.5mm.

We offer precise turning and milling services to produce completed components per customer drawings. Critical parts of the implant are machined in CNC machining centers with a dimensional tolerance of +0.02mm.

Surface treatment options: electropolishing, passivation, anodising These secondary processes boost corrosion resistance and give visual identifying coding for surgical equipment sets.

Heat treatment schedules are designed to obtain the best microstructure for a given application. Cold working can leave residual stresses, however these are eliminated by stress-relief annealing without loss of mechanical characteristics.

Laser tagging services offer permanent traceable labelling. We adhere to FDA and EU Medical Device Regulation regulations by printing unique device identifiers (UDI) directly on final components.

Procurement Guidance and Material Certification

When buying professional medical devices, it is necessary to thoroughly check the documentation. Material test certificates according to EN 10204 3.1 are delivered with each consignment.

These certificates provide heat number traceability, complete chemical analytical results and mechanical test data . Special emphasis is given to the concentrations of interstitial elements such as oxygen, nitrogen and hydrogen that influence ductility and biocompatibility.

Verification of tensile test results for yield strength, ultimate tensile strength and elongation values on a lot-by-lot basis. We don’t hide behind minimum specification criteria, we present real measured values for full transparency.

Grain size analysis and photomicrographs of microstructure support key application orders. This documentation is for customer receiving inspection and regulatory filing.

FAQ

Q: What distinguishes ASTM F67 GR1 from other commercially pure titanium grades?

A: GR1 contains the lowest interstitial element content among F67 grades. Maximum oxygen of 0.18% provides optimal ductility and cold-forming characteristics compared to GR2 (0.25% O), GR3 (0.35% O), and GR4 (0.40% O).

Q: How does hydrogen content affect medical titanium performance?

A: Hydrogen exceeding 0.015% causes embrittlement that reduces ductility and fatigue resistance. This phenomenon leads to unexpected brittle fracture under cyclic loading conditions typical in orthopedic implants. Our manufacturing process controls hydrogen pickup during melting and processing.

Q: Is ASTM F67 GR1 suitable for load-bearing implants?

A: While GR1 offers excellent biocompatibility, its lower strength makes it more appropriate for low-stress applications like dental abutments and thin bone plates. High-load applications such as hip stems typically require Ti-6Al-4V ELI alloy (ASTM F136) for adequate fatigue strength.

Q: What surface finish specifications should be specified for medical bars?

A: Centerless ground or peeled surfaces with Ra < 0.8µm remove the oxygen-enriched alpha case layer. This preparation ensures consistent machining behavior and eliminates potential brittle surface layers that compromise fatigue performance.

Q: Can you provide small quantity orders for prototype development?

A: Yes, we accommodate prototype and small-batch requirements starting from 10kg minimum order quantities. This flexibility supports medical device development timelines and regulatory submission sample preparation.

Q: What documentation supports FDA 510(k) or EU MDR submissions?

A: We provide material test reports, ISO13485 certificates, biocompatibility test summaries (ISO 10993), and Declaration of Conformity documents. Our quality system documentation demonstrates manufacturing process validation and statistical process control implementation.
