Ti-6Al-4V ELI Plate (ASTM F136, AMS 4907) | Medical & Aerospace Grade Titanium

Introduction to 6AL-4V ELI Titanium (ASTM F136)

6AL-4V ELI Titanium, also known as Grade 23 Titanium, is a high-performance titanium alloy known for its biocompatibility, high strength, and corrosion resistance. As an enhanced version of Grade 5 Titanium, this alloy has a lower level of impurities, making it particularly suited for medical applications such as implants. It's also used in aerospace and marine industries where strength and resistance to harsh environments are essential.

​​​​​​​Our Ti-6AL-4V Eli Plate represent the premium grade of Grade 5 titanium, specially engineered with reduced oxygen/iron content for superior ductility and fracture toughness. Certified to ASTM F136, AMS 4907, and ISO 5832-3, these plates are essential for:

✔ Medical Implants – Hip joints, bone screws, cranial plates (FDA-approved)
✔ Aerospace Structures – Airframe components requiring enhanced fatigue life
✔ Deep Sea Equipment – Submersible housings resistant to hydrogen embrittlement
✔ Military Applications – Ballistic armor with optimal strength-to-weight ratio

Chemical Composition (ASTM F136 Requirements)

Element Composition (%) ELI Advantage
Titanium (Ti) Balance -
Aluminum (Al) 5.5-6.5 Tight control prevents brittleness
Vanadium (V) 3.5-4.5 Enhances strength retention
Oxygen (O) ≤0.13 (vs 0.20 max in standard) Improves fracture toughness
Iron (Fe) ≤0.25 (vs 0.30 max in standard) Reduces fatigue crack initiation
Carbon (C) ≤0.08 Minimizes carbide formation
Nitrogen (N) ≤0.05 Prevents nitride embrittlement

Technical Advantages vs Standard Ti-6Al-4V

1. Enhanced Reliability for Medical Implants

  • Lower Young's Modulus (110 GPa vs 114 GPa): Better matches bone stiffness to prevent stress shielding

  • Controlled Alpha Case: <5μm layer after heat treatment (vs 15-20μm in standard)

2. Superior Performance in Extreme Environments

  • Cryogenic Applications: Maintains ductility down to -253°C (liquid hydrogen service)

  • Stress Corrosion Threshold: 80% of yield strength (vs 60% for standard grade)

3. Optimized Manufacturing Characteristics

  • Improved Weldability: Reduced porosity in EB welds

  • Better Machinability: 15% longer tool life vs standard alloy


Industry Applications with Verified Performance
