GR23 Titanium Plate Medical Grade
Baoji Yibaite New Materials Technology Co., Ltd. specializes in supplying Grade 23/TC4 ELI medical-grade titanium plates (GR23). The company is located in "China Titanium Valley" - Baoji, and is a high-tech enterprise dedicated to the processing and sales of titanium alloys.
GR23 is known as the "gold standard" of implantable titanium alloys, featuring a low-interstitial-element (ELI) version of Ti-6Al-4V with strictly controlled oxygen, nitrogen, hydrogen, and iron content to maximize ductility, fracture toughness, and fatigue crack growth resistance. This material delivers an exceptional combination of high tensile strength (≥ 860 MPa), superior biocompatibility, and outstanding corrosion resistance in bodily fluid environments. Our titanium plates are fully compliant with ASTM F136 and ISO 5832-3 implant material standards, making them the preferred material for orthopedic implants, dental implant components, surgical instruments, cardiovascular devices, and spinal fixation systems.
Products Description
Optimal implant-grade strength & fracture toughness
- Strictly controlled low interstitial elements (ELI): oxygen ≤ 0.13%, carbon ≤ 0.08%, nitrogen ≤ 0.05%, hydrogen ≤ 0.012%.
- Tensile strength ≥ 860 MPa with elongation ≥ 10%, delivering higher fatigue crack growth resistance and fracture toughness than standard GR5 - critical for load-bearing implant applications.
Proven Biocompatibility & Physiological Inertness
- Surgical Grade Safety: Highly non-toxic, non-magnetic, and fully biocompatible with human tissue and bone matrix, presenting no risk of toxic metal ion leaching or adverse rejection in vivo.
- Corrosion Resistance: Immune to chemical attack from bodily fluids, aggressive physiological media, seawater, and harsh pharmaceutical solvents, making it the premier choice for long-term clinical exposure.
Full medical material certification
- Base material fully compliant with ASTM F136 / ISO 5832-3 for wrought Ti-6Al-4V ELI implant material.
- ASTM B265 dimensional and mechanical property requirements for titanium plate.
- EN 10204 3.1 Material Test Certificate provided with every order, reporting full traceable chemistry and mechanical data.
- Production facility operates under ISO 9001 and ISO 13485 quality management systems.
Stable Machinability & Formability
- Processing Compatibility: Responds exceptionally well to precision waterjet cutting, CNC machining, wire EDM, laser cutting, and stamping blanks.
- Stress-Relief Annealed: All plates undergo professional vacuum stress-relief annealing to eliminate internal residual tension, ensuring excellent flatness during subsequent machining and forming without distortion.
Excellent machinability for precision implant manufacturing
- Responds well to CNC milling, wire EDM, laser cutting, and precision grinding - the standard processes used in orthopedic and dental implant production.
- Good weldability via TIG and electron beam welding for surgical instrument assemblies.
- Surface can be polished to mirror finish (Ra ≤ 0.4 μm) for implant contact surfaces or sandblasted / acid-etched to promote bone ingrowth on osseointegration surfaces.
Tried and trusted by the global medical device supply chain
- Plates from our facility have been supplied to orthopedic implant manufacturers, dental implant producers, surgical instrument OEMs, and spinal device companies in over 30 countries.
- Raw material sourced from certified sponge titanium producers, melted in VAR (Vacuum Arc Remelted) furnaces to ensure ultra-low inclusion content and maximum purity.
- Every plate is individually inspected - chemistry, mechanicals, dimensions, surface quality - before release to the customer.

Application Fields
- Orthopedic implant manufacturing: Hip joint replacement femoral stems and acetabular cups, knee replacement femoral and tibial components, trauma fixation bone plates, intramedullary nails, and orthopedic cortical and cancellous screws.
- Spinal fixation and fusion systems: Anterior cervical plates, pedicle screw rod systems, interbody fusion cages, spinal hooks, and vertebral body replacement implants where fatigue life and fracture toughness are critical.
- Dental implant and maxillofacial surgery: Dental implant fixture blanks, abutment components, jaw reconstruction plates, orbital floor reconstruction meshes, and cranial defect repair custom plates produced via CNC machining from GR23 plate stock.
- Surgical instruments and operating room equipment: Reusable surgical retractors, bone cutting guides, instrument trial implants for intraoperative sizing, sterilization trays, and minimally invasive surgical tool shims - all requiring repeated autoclave sterilization without material degradation.
- Cardiovascular and soft tissue implant devices: Pacemaker and defibrillator titanium housing components, heart valve structural frames, vascular stent precursor tube blanks, and cochlear implant enclosures where long-term biocompatibility inside the human body is non-negotiable.
- Medical device OEM and contract manufacturing: OEM implant system production for orthopedic and dental brands, custom-machined patient-specific implant plates from CT/CAD data, and prototyping for next-generation implant designs - all sourced from ASTM F136 certified GR23 plate stock with full EN 10204 3.1 traceability.
FAQ
Q: Are you a manufacturer or a trading company?
A: We are a professional and experienced titanium products manufacturer in China.
Q: Can you provide customized processing?
A: Yes. Baoji Yibaite supports cutting, bending, stamping, CNC machining, and deep drawing according to customer drawings.
Q: What is the delivery time?
A: Regular size in stock within 3–7 days; customized production about 10–15 working days.
Q: What standards do your GR23 titanium plates comply with?
A: Our GR23 titanium plates meet ASTM F136 for wrought Ti-6Al-4V ELI surgical implant material and ASTM B265 for titanium and titanium alloy strip, sheet, and plate dimensional specifications. The base material is Grade 23 titanium alloy (Ti-6Al-4V ELI). Every plate comes with a full Material Test Certificate following EN 10204 3.1. The certificate reports traceable chemical composition in full detail. Interstitial elements are strictly controlled - oxygen ≤ 0.13%, carbon ≤ 0.08%, nitrogen ≤ 0.05%, hydrogen ≤ 0.012% - to maximize ductility and fracture toughness for implant service. Mechanical properties are also reported, with tensile strength ≥ 860 MPa, yield strength ≥ 795 MPa, and elongation ≥ 10%. Every plate undergoes 100% dimensional inspection covering thickness, width, length, flatness, and surface condition. Microstructure examination can be added as an option to verify uniform equiaxed alpha grain size per ASTM F136 requirements. PMI (Positive Material Identification) testing is also available on finished plates for medical device OEM customers who require full alloy verification before committing material into implant production. Production runs under ISO 9001 and ISO 13485 quality management systems in our facility in "China Titanium Valley" (Baoji).
Q: What surface finishes are available?
A: Pickled surface, polished, brushed, sandblasted, and mirror finish are all optional.
