Titanium Ti-6Al-4V (Grade 5), Annealed Bar
Categories:	Metal; Nonferrous Metal; Titanium Alloy; Alpha/Beta Titanium Alloy
Material Notes:	Information provided by Allvac and the references. Annealing Temperature 700-785ºC. Alpha-Beta Alloy Applications: Blades, discs, rings, airframe, fasteners, components. Vessels, cases, hubs, forgings. Biomedical implants. Biocompatibility: Excellent, especially when direct contact with tissue or bone is required. Ti-6Al-4V's poor shear strength makes it undesirable for bone screws or plates. It also has poor surface wear properties and tends to seize when in sliding contact with itself and other metals. Surface treatments such as nitriding and oxidizing can improve the surface wear properties. 4 other heat treatments of this alloy are listed in MatWeb.
Key Words:	Ti-6-4; UNS R56400; ASTM Grade 5 titanium; Ti6Al4V, Ti64, biomaterials, biomedical implants, biocompatibility
