Product Overview
GR23 medical titanium rod is a titanium alloy rod specially developed for permanent implantation in surgery. The material is Ti6Al4V ELI, with national standard TC4ELI. It belongs to the α+β type titanium alloy with ultra-low interstitial elements. This material complies with ASTM F136 and ISO 5832-3 implantation grade standards, strictly controlling oxygen, hydrogen, nitrogen, and carbon interstitial impurities. The oxygen content is controlled less than 0.13%.
The product has undergone forging, rolling, precise annealing and non-destructive testing. The dimensional tolerance is precise and the surface is clean without impurities, and it is suitable for CNC precision machining. It can be processed into bone screws, bone plates, intramedullary nails, spinal screws and rods systems, artificial joint components, dental implants, and maxillofacial restoration prostheses, etc., which are long-term human implant devices. It is the preferred base material for high-load implant components in orthopedics, maxillofacial surgery, and dentistry.

Technical Advantages
ELI Extra‑Low Interstitial Formula
Strict control of O/H/N/C impurities. Fracture toughness is 25‑30% higher than standard Grade5, excellent fatigue crack growth resistance, lowering implant failure risk under long‑term human cyclic loading.
Excellent Biocompatibility
Resists corrosion in body fluid environment, low ion release, MRI‑safe, qualified for permanent implantation.
Superior Machinability
Homogeneous stable annealed microstructure, good performance for CNC turning, milling and drilling for high‑precision medical components.
Bone‑like elastic modulus
This feature can reduce the stress shielding effect and facilitate bone integration.
Medical‑grade quality control
Vacuum‑consumable‑remelting ingot source, full‑batch NDT inspection, complete traceable documentation to meet medical device manufacturer compliance requirements
Typical Application
Orthopedics trauma
bone screws, bone plates, intramedullary nails, external fixator components
Spinal implants
pedicle screws, spinal fixation rods, interbody fusion cages
Joint replacement
hip stem, knee prosthesis substrates
Craniomaxillofacial surgery
pedicle screws, spinal fixation rods, interbody fusion cages
Dental
