Featuring 6% Al, 4% V, and extra low interstitials (ELI), this titanium alloy is the most popular titanium alloy we offer. Interstitial elements such as iron and oxygen are tightly controlled during the melt process in order to improve the ductility and fracture toughness of this alloy. Due to its improved mechanical properties and added strength, this alloyed titanium is a durable choice for medical devices and implants.
