Ti 6Al-4V Eli is one of the most commonly used titanium alloy. Neither this or Ti-6Al has corrosion properties quite as good as CP titanium but both of these grades are corrosion resistant to be used in seawater and oxidizing acids.

6AL-4V ELI is certified to ASTM F136 and is generally known as implant grade 6-4 Titanium. It is well suited for implants and medical devices due its properties of biocompatibility, corrosion resistance, high strength and toughness.

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 .13% which gives the material an improved toughness.

This material is low interstitial version of Ti-6Al-4V, for maximum toughness. This grade is normally used in the annealed condition.

Stress relief 900-1200°F 1 to 4 hours, air cool. Duplex anneal, bar and forgings: Solution anneal 50-100°F below the beta transus, hold 1 hour minimum, air cool. Then reheat within the range 1300-1400°F, hold 1 hour minimum, air cool. Stress - relief annealing is performed after welding.

Applications:

Aerospace, Chemical processing, cryogenics vessels, medical, orthopedic implants, dental implants, bone and joint replacement, dental root implants, surgical clips.
