6Al-4V ELI is one of the most widely used Titanium alloys in the medical industry. It is certified to ASTM F136, and commonly referred to as implant grade 6-4 Titanium. It's properties of biocompatibility, corrosion resistance, high strength, and toughness make it especially suitable for implants and other medical devices.
The main difference between Ti-6Al-4V ELI (Grade 23) and Ti-6Al-4V (Grade 5) is that in ELI (Extra Low Interstitials) the maximum oxygen content is lowered to 0.13%. This gives the material an improved fracture toughness.
Among it's uses in the medical industry are:
- Orthopedic implants
- Bone and Joint Replacement
- Dental root implants
- Surgical Clips
- Cryogenic Vessels
6AL-4V ELI is also referred to as:
- Grade 23 Titanium
- ASTM F136
6Al-4V ELI is one of the most widely used Titanium alloys in the medical industry. It's properties of corrosion resistance, high strength, and toughness make it especially suitable for implants and other medical devices.
It's excellent strength to weight ratio also makes it ideal for aerospace applications.
