ASTM F136 Titanium Alloy Bars

ASTM F136 is the definitive standard for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for surgical implant applications. ASTM F136 titanium alloy bars and rods conforming to this standard represent the premium grade of Ti6Al4V (Extra Low Interstitial) alloy used for the most critical, permanent, and load-bearing medical implants due to its superior biocompatibility, excellent fatigue strength, and enhanced fracture toughness.

1. Superior Biocompatibility: The "ELI" chemistry minimizes the risk of adverse tissue reactions and promotes better osseointegration (the direct structural and functional connection between living bone and the surface of the implant).
2. Excellent Fatigue Strength: Implants such as hip joint stems and spinal rods are subjected to millions of cycles of loading. The more pure microstructure of the "Ti6Al4V ELI" material gives it excellent fatigue failure resistance, ensuring its long-term durability in the body.
3. Enhanced Fracture Toughness: This refers to the material's ability to resist crack propagation. The "Ti6Al4V ELI" material has a lower content of interstitial elements, making it more robust than the standard 5-grade material. This means it can withstand minor defects or impacts without suffering catastrophic damage.
4. High Ducility: The material can be bent and contoured to a degree without cracking. This is crucial for surgeons who may need to adjust a bone plate during surgery to fit a patient's anatomy perfectly.

ASTM F136 titanium alloy bars are machined into the most demanding surgical implants:

• Orthopedic Implants: Hip stems, femoral knee components, trauma plates, intramedullary nails.
• Spinal Implants: Interbody fusion cages, pedicle screws, rods, and plates.
• Dental Implants: Implant fixtures and high-strength abutments.
• Cranio-Maxillofacial (CMF): Patient-specific implants for facial reconstruction.
