Commercially pure Zirconium 702 exhibits good ductility even at cryogenic temperatures. It has good strength comparable with other common engineering alloys. Zirconium is a reactive metal that has a high affinity for oxygen resulting in the formation of a protective oxide layer in air at room temperature. This protective oxide gives zirconium alloys their superior corrosion resistance.

Zirconium 702 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.
Refer to NACE (National Associate 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.
Cut to lengths
