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 3 can only be hardened by cold work
