Product Introduction
Product Introduction
Medical Titanium Rod Gr5 ELI (also known as Gr23, UNS R56401) is a high-performance biomedical titanium alloy material used for manufacturing surgical implants, prostheses, artificial organs, and therapeutic medical devices.
Gr5 ELI (Extra Low Interstitial) is an optimized version of Ti-6Al-4V with reduced oxygen and iron content, offering superior ductility and fracture toughness compared with standard Grade 5 titanium. It combines:
High specific strength
Excellent fatigue resistance
Outstanding corrosion resistance
Elastic modulus closer to human bone
Superior biocompatibility
It is widely recognized as one of the most important materials for surgical implant applications under ASTM International F136 specification.
Classification of Biomedical Titanium Alloys
Based on microstructure, biomedical titanium alloys can be classified into:
α Titanium Alloy
α + β Titanium Alloy (Gr5 ELI / Gr23)
β Titanium Alloy
TiNi Shape Memory Alloy
Compared with medical stainless steel and cobalt-based alloys, titanium alloys offer:
Lower density
Higher strength-to-weight ratio
Better corrosion resistance
Lower elastic modulus
Excellent biocompatibility
Easier machining
Applications
Gr5 ELI titanium rods are widely used in:
Orthopedic Applications
Bone screws
Bone plates
Intramedullary nails
Spinal fixation rods
External fixators
Hooks and connectors
Joint Replacement
Hip joint prostheses
Knee joint implants
Artificial joint frameworks
Cardiovascular & Active Implants
Pacemaker components
Defibrillator components
Stents
Surgical Instruments
Bone drills
Bone saws
Bone reamers
These devices are designed to stabilize fractured bones, correct deformities, and support healing during surgical procedures.
