Ti 6Al-4V Eli

UNS #R56407

Ti 6Al-4V ELI is the extra-low interstitial version of Ti 6Al-4V and its content is arrived at by the careful selection of ingot raw materials with lower specified limits on iron and the interstitial elements C and O. It has been the material of choice for many medical and dental applications due to its excellent biocompatibility, good fatigue strength, and low modulus. The ELI grade has superior damage tolerance (fracture toughness, fatigue crack growth rate) and better mechanical properties at cryogenic temperatures compared to standard grade Ti 6Al-4V. The high-purity alloy is also known as ASTM B348 Grade 23.
