ASTM F136
ASTM F136 – Premium 6Al-4V ELI Titanium Alloy
ASTM F136 is the globally recognized standard specification for wrought titanium-6aluminum-4vanadium ELI (Extra Low Interstitial) alloy, primarily used in surgical implants and medical devices. Known for its exceptional biocompatibility, strength, and corrosion resistance, this alloy meets the demanding requirements of modern healthcare and engineering.
What Is ASTM F136 Titanium?
ASTM F136 defines the chemical, mechanical, and metallurgical requirements for Ti-6Al-4V ELI — the “extra low interstitial” grade used for long-term human implantation. Lower limits on oxygen, nitrogen, carbon, and hydrogen improve toughness and biocompatibility, making it a trusted material for orthopedic and dental implants.
Chemical Composition (Typical Limits)
| Element | Typical Range / Max |
|---|---|
| Titanium (Ti) | Balance |
| Aluminum (Al) | 5.5 – 6.5% |
| Vanadium (V) | 3.5 – 4.5% |
| Oxygen (O) | ≤ 0.13% |
| Carbon (C) | ≤ 0.08% |
| Nitrogen (N) | ≤ 0.05% |
| Hydrogen (H) | ≤ 0.012% |
| Iron (Fe) | ≤ 0.25% |
Key Properties of ASTM F136 Titanium
Superior Biocompatibility
Non-toxic and non-reactive → very low risk of allergic response or rejection in long-term implants
High Strength & Fatigue Resistance
Minimum UTS ≈ 120–125 ksi with exceptional fatigue strength for cyclic, load-bearing components
Exceptional Corrosion Resistance
Protective oxide film resists attack from body fluids and harsh sterilization environments
Applications of ASTM F136 Titanium
Surgical Implants
Orthopedic plates & screws
Spinal fixation & trauma implants
Dental implants & abutments
Medical Instruments
Lightweight, strong, corrosion-resistant tools with long sterilization life
Aerospace & High-Performance Engineering
Critical parts where strength-to-weight and fatigue performance are essential
ASTM F136 vs Other Titanium Grades
| Material | Where It Excels |
|---|---|
| Commercially Pure Ti (Gr 1–2) | Excellent corrosion resistance, moderate strength |
| ASTM F136 (Ti-6Al-4V ELI) | Higher strength + better toughness for load-bearing implants and aerospace hardware |
