Description
📦 ASTM F136 Titanium Bar – GR23 Ti-6Al-4V ELI for Surgery
For GR23 Ti-6Al-4V ELI bar, specify diameter, length, quantity, delivery condition, ASTM F136 edition, surface finish and dimensional tolerance. State any additional standard, melt-route, traceability, test frequency and document requirements. Confirm the raw-material acceptance scope separately from finished-device design and approval.
Prepare the material purchasing requirements, review ASTM F67 Grade 4 titanium rod as a separate listing, or request a quotation. A different grade is not an automatic substitute.
📝 Introduction
ASTM F136 titanium bar is GR23 Ti-6Al-4V ELI raw material. Confirm the required standard edition, delivery condition, dimensions and batch acceptance documents. If ISO 5832-3 is also specified, its requirements must be reviewed separately; neither the alloy name nor the listing establishes approval for a finished implant.
🔬 Material Overview
-
Material Name: Titanium Alloy GR23 (Ti-6Al-4V ELI)
-
Material requirements: specify the ASTM F136 edition and condition. State any additional ISO 5832-3 requirements separately and confirm conformity documents for the actual order.
-
Purity Level: Extra Low Interstitial for enhanced ductility and fracture toughness
-
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 |
ELI designation must be supported by composition and test records for the batch. Fracture, fatigue and implant-design requirements need relevant application-specific data.
⚙️ 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
Corrosion and ion-release requirements must be evaluated for the actual material condition, surface and finished-device exposure. A material listing does not establish patient safety or permanent-implant suitability.
🏥 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
Medical-device acceptance and safety validation are the responsibility of the applicable device design and manufacturing process. Specify the raw-material and documentation requirements separately.
