Medical Grade Titanium Bar (ASTM F136) For Surgical Implants
Suitable for long-term implantation with minimal risk of rejection or adverse tissue reaction.
High Strength & Lightweight
Offers outstanding mechanical strength while remaining significantly lighter than stainless steel materials.
Extra Low Interstitial (ELI) Composition
Lower oxygen and impurity content improves toughness, ductility, and implant safety.
Superior Corrosion Resistance
Maintains stable performance in body fluid environments and resists corrosion over extended periods.
Precision Machining Capability
Ideal for manufacturing orthopedic implants, dental implants, trauma fixation devices, and surgical instruments with high dimensional accuracy.
Medical implant-grade titanium alloy round bars (ASTM F136, Ti-6Al-4V ELI) are core raw materials specifically developed for surgical permanent implant devices. Unlike conventional Grade 5 industrial titanium bars and ordinary pure titanium bars, they undergo strict control over interstitial elements such as oxygen, nitrogen, and carbon, emphasizing low allergenicity, high toughness, and long-term implant safety. Primarily used for precision machining of orthopedic, neurosurgical, and oral surgical implants, these bars are the preferred medical base material for global high-end surgical device manufacturers.
ASTM F136 Grade 23, designated as ELI low-interstitial titanium alloy for implantation, features a tensile strength of ≥860 MPa, yield strength of ≥795 MPa, and elongation of ≥10%. Compared to standard Grade 5 titanium alloy, it exhibits lower impurity levels, superior fatigue resistance, and reduced metal ion release post-implantation. It has been subjected to high standard ISO13485 biocompatible test, showing no cytotoxicity and long-term stay in human body. Good machinability allows precision machining (such as turning, grinding and milling), and high final product accuracy.
Application Scenarios and Dimensional Parameters
| ASTM Grade | Alloy Type | Diameter | Length | Tolerance | Surface Finish | Application |
|---|---|---|---|---|---|---|
| F136 Gr23 | Ti‑6Al‑4V ELI | 2–20 mm | 50–3000 mm | ±0.04 mm | Polished / Electropolished | Surgical permanent implants |
Orthopedic surgical implants: Φ4–12 mm, suitable for micro bone screws, fixation anchors, and spinal connectors, featuring high strength and fatigue resistance;
Oral Implantology: Φ6–16 mm, suitable for implant bodies and abutment blanks, corrosion-resistant and adapted to masticatory forces;
Precision neurosurgical implantation: Φ2–6 mm, suitable for neural fixation devices and intracranial micro-implants, featuring precise dimensions and high safety;
Customized surgical accessories: Support non-standard diameters, tolerances, and lengths for customization, with options for chamfering and deburring as required, suitable for niche surgical instrument development.
