Commercially Pure Titanium Grade 4 Alloy Description
Of all the commercially pure grades, Titanium Grade 4 has the highest strength. This alloy combines excellent corrosion resistance with good formability and weldability. Generally chosen for its corrosion resistance in a variety of chemical process equipment as well as marine and airframe applications. It can be used for parts requiring strength up to 400°F and oxidation resistance to 600°F.

Commercially Pure Titanium Grade 4can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.
Additional Properties
Corrosion Resistance
Refer to NACE (National Association of Corrosion Engineers)for recommendations.
Standard Wire Finishes
Extra Clean: (XC) Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”
Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications
Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation. A soap finish is available in tempered products.
Plated: Many plating options are available.
∗Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.
Forms
Continuous Coils
Cut to lengths
Precision cutting
Heat Treatment
Commercially Pure Titanium Grade 4can only be hardened by cold work
