Ti 6Al-4V is the most widely used of all the alpha-beta titanium alloys. It is typically used in the annealed condition, at service temperatures through 750°F. However it may be heat treated for high strength in sections under 4” thick. Hardenability is limited and sections over one inch may not develop full properties. Ti 6Al-4V is welded with either matching or ELI (Extra Low Interstitials) filler wire.
