ATI 6-6-2 (UNS R56620) is a highly beta-stabilized, two-phase, alpha-beta titanium alloy which is a modification of the Ti-6Al- 4V system. Because of the higher beta stabilizing elements (additional vanadium plus iron and copper), this alloy has a higher strength potential than ATI Ti-6Al-4V alloy, but at a sacrifice of weldability and toughness. In most cases, the welding of ATI 6-6-2 is not recommended. It can be used in the annealed or solution treated and aged conditions. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on forming, heat treating, machining, and joining. Filing Code: Ti-189. Producer or source: ATI.
