Trade Name
Ti 6Al-4V (ELI)
DescriptionTi-Grade 23; Titanium - 6%Al - 4%V, extra low interstitial, (ELI)
Special PropertiesTi-Grade 23 ELI is a variant of Ti-Grade 5 and is used in medical technology because of its good biocompatibility and excellent fracture toughness and crack propagation behavior. It maintains its good toughness even at low temperatures down to –253 °C. These properties, as well as its low elastic modulus and good fatigue strength are due to the alloy‘s relatively low contents of tramp elements such as oxygen and iron (Extra-Low Interstitials).
