Titanium Grade23, Ti-6Al-4V-ELI

Titanium Grade23(UNS R56401) is an alpha-beta alloy based on Grade 5. It is the higher purity version of grade 5 by reducing the amount of interstitial elements (O, N, C) and improved stress corrosion cracking. The properties of good strength, lightweight, good corrosion resistance and high toughness making it especially suited for thick-wall highly stressed parts such as the ultimate dental and medical application. LKALLOY is a leading supplier and manufacturer of grade Ti-6Al-4V-ELI material. LKALLOY mainly supply Titanium Grade23 tubing, Titanium Grade23 sheet and Titanium Grade 23 round bar in various size and specifications.
