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.

Iron + Chromium: 0.2 max
Hydrogen: 0.005 max
Nitrogen: 0.025 max
Carbon: 0.05 max
Oxygen: 0.16 min

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.
