Titanium 6-6-2 (6Al-6V-2Sn) is a heat treatable, high strength titanium alloy with higher strength and section hardenability that 6Al-4V. but with lower toughness and ductility and limited weldability. 6-6-2 is typically used in airframe component applications.
Standard Specification:
AMS 4971 bars, rings, forgings (annealed, heat treatable)
AMS 4978 bars, rings, forgings (annealed)
AMS 4979 bars, rings, forgings (annealed & precipitation heat treated)
AMS 6935 bars, forgings (solution treated & aged)
