-
Form: Round bars, square bars, and custom profiles
-
Surface Condition: Polished, turned, or centerless ground finish
Chemical Composition (Typical):
| Element | Content (%) |
|---|---|
| Titanium (Ti) | Balance |
| Aluminum (Al) | 5.50 – 6.50 |
| Vanadium (V) | 3.50 – 4.50 |
| Oxygen (O) | ≤ 0.13 |
| Nitrogen (N) | ≤ 0.05 |
| Carbon (C) | ≤ 0.08 |
| Iron (Fe) | ≤ 0.25 |
| Hydrogen (H) | ≤ 0.0125 |
✅ The Extra Low Interstitial (ELI) content ensures superior fracture toughness, making it ideal for load-bearing medical implants.
⚙️ Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength (MPa) | ≥ 860 |
| Yield Strength (MPa) | ≥ 795 |
| Elongation (%) | ≥ 10 |
| Reduction of Area (%) | ≥ 25 |
| Hardness (HRC) | ≤ 36 |
| Modulus of Elasticity (GPa) | ~ 110 |
These mechanical properties make the GR23 titanium bar suitable for applications requiring a combination of high strength and fatigue resistance, while maintaining excellent formability for custom surgical designs.
🛡 Corrosion Resistance
The ASTM F136 Titanium Bar demonstrates outstanding corrosion resistance in physiological environments such as saline solutions and blood plasma. Its naturally forming oxide film acts as a protective barrier, preventing metal ion release and ensuring patient safety. This makes it an ideal medical titanium rod for permanent implantation.
🏥 Applications in Medical Field
-
Orthopedic Implants: Hip and knee replacement components, bone fixation plates, spinal rods
-
Dental Implants: Abutments, screws, and support posts
-
Surgical Instruments: High-precision cutting tools and orthopedic instruments
-
Trauma Fixation Devices: Screws, pins, and external fixation rods
-
Cardiovascular Devices: Pacemaker housings and stent components
Its biocompatibility, combined with fatigue strength, ensures that Ti-6Al-4V ELI titanium bar products meet the highest safety standards in the medical industry.
