Titanium Grade 23
Ti6Al4V ELI (Grade 23) is a titanium alloy with aluminium and vanadium. It is a purer version of the standard TA6V alloy. Interstitial element contents (iron, oxygen and carbon) are strictly controlled and limited during the fusion process. This purity grants the metal: improved mechanical properties and greater resistance to fatigue.
Description
Titanium alloys are divided into three main groups: alpha-phase, beta-phase, and alpha-beta-phase. Grade 23 Ti 6Al 4V ELI alloy is an alpha-beta wrought alloy. The ELI stands for extra low interstitial. For an alloy to be branded as an ELI product, it should be produced as such at the mill.
