Applications of Grade 9 Titanium

Description of Grade 9 Titanium

Titanium Alloy 3-2.5 (Grade 9 or Half 6-4) is a medium strength alloy with good weldability and fabricability for mildly reducing to mildly oxidizing media. It is a compromise between the facility of welding and manufacturing of the pure grades and the high strength of Grade 5. Containing 3% Aluminum and 2.5% Vanadium, it has great corrosion resistance and can be used extensively in aerospace, chemical processing, medical, marine, automotive.

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.
