RMI 6A1-6V-2Sn is an alpha-beta titanium alloy that provides a tensile strength of 150,000 psi in the mill-annealed condition in section sizes up to 2 inches. It offers good corrosion resistance in applications requiring high strength-to-weight ratios at temperatures up to 750 F. Among its uses are rocket engine cases and ordnance components. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and bend strength as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Ti-79. Producer or source: RMI Company.

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.
