Common Name
Ti-6Al-4V ELI Ti 6-4 ELI
Grade 23 Titanium
General Information
Ti-6Al-4V alloy is the most widely used titanium alloy of the alpha-plus-beta class, and is also the most common of all titanium alloys. This modification incorporates extra low interstitial (ELI). The wrought material is used in applications where moderate strength, good strength to weight, and favorable corrosion properties are required. This alloy is commonly used in medical implants where strength is important. The alloy is available as castings, wire, bar, plate, sheet, forgings, rings, and billet.
