(Commercially Pure Titanium: Grade 3) TI50A Strip, Coil, Foil, Wire,
ASTM B265 GR3, AMS 4900K, ASTM F67, MIL-T-9046CP2


Bellows, aircraft structural, honeycomb, gaskets, aircraft skin, heat exchanger parts


Commercially Pure Titanium Grade 3 offers slightly higher mechanical properties than Grade 2, while displaying similar ductility and formability. Generally used where corrosion resistance is a major design factor in chemical production components, marine and airframe applications. It can be used for parts requiring strength up to 400 ° F and oxidation resistance to 600 ° F.

Additional Properties

Corrosion Resistance

Refer to NACE (National Associate of Corrosion Engineers) for recommendations.


#1 - Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D - Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.
#2B - Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA - Bright annealed cold rolled and bright annealed
#CBA - Course bright annealed cold rolled matte finish and bright anneal
#2 - Cold Rolled
#2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part.
Polished - Various grit finish for specific polish finished requirements.

* Not all finishes are available in all alloys- Contact Ulbrich Sales for more information.

Wire Finishes

XC - Extra clean. Bright annealed or bright annealed and cold rolled Grease - Ultra bright finish for decorative applications
Soap - Soap is not removed from tempered wire to act as a lubricant. * Contact Ulbrich Wire for custom finishes.

Heat Treatment

Titanium Grade 3 can only be hardened by cold work.
