Titanium Alloy 6-4 facts

The most common titanium alloy. An alpha-beta alloy, it is hardenable by heat treatment.Used for applications requiring excellent fracture toughness and fatigue strength such as aircraft, structural components, blades, discs, rings, airframes, fasteners, components, vessels, cases, hubs, forgings, biomedical implants and devices. Biocompatibility: Excellent, especially when direct contact with tissue or bone is required. Ti-6Al-4V's poor shear st... more
