ULTIMET® can 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
