TA6V ELI, also known by its name of Grade 23, is a titanium alloy with aluminium and vanadium. It is a purer version of the standard TA6V alloy. Interstitial element (iron, oxygen and carbon) content in this alpha + beta alloy is strictly controlled and limited during the fusion process. This purity grants the metal improved mechanical properties and greater resistance to fatigue. The TA6V ELI is especially popular due to its ductility at cryogenic temperatures and its excellent biocompatibility with the human body, making it an essential material in the manufacture of medical implants (surgical, dental, etc.). It is also widely used in the aeronautic and industrial sectors, such as jewellery and watch-making.
