Characteristics of Titanium 6-6-2

This grade of titanium alloy can be heated treated to higher strengths and heavier section sizes compared to that of Ti-6AL-4V. Ti-6-6-2 possesses excellent strength, corrosion resistance, and a medium level of fabricability. 

Working with Titanium 6-6-2

Titanium 6-6-2 is readily finish-forged from 1650°F (899°C) with a minimum finishing temperature of 1,400°F (760°C). Minimum reductions of about 35% in the alpha-beta range are recommended to obtain specification properties. 

This product can be difficult to cold form due to its high strength and large amount of springback. Annealed material may be hot-formed up to 1,500°F (816°C). Hot sizing or creep forming is generally performed at 1,000 - 1,300°F (538 - 704°C), however, any heating above 1,100°F (593°C) results in surface contamination and the contaminated layer must subsequently be removed by machining or proper pickling. 

Titanium 6-6-2-can be successfully welded using the inert gas shielded, fusion-welding process, but the heat affected zone will have considerably lower ductility and toughness compared to the parent metal. Some improvement in ductility can be obtained by using commercially pure titanium filler wire to dilute the beta-stabilizing elements, and by using a post-weld treatment.
