Ti-6AL-4V ELI Titanium Bar, Plate - AMS 4930, 6932
Ti-6AL-4V ELI, AMS 4930, is a general purpose alpha-beta alloy. The ELI (extra low interstitials) variant possesses high cycle fatigue strength and is available for fracture critical applications, such as medical implants or aerospace applications. Titanium Grade 23 material is biocompatible, features moderately high tensile strength, improved ductility, good fatigue strength, intermediate fracture toughness, and high resistance to general corrosion in seawater. It is hardenable in sections up to 1" thick.
