Pure Zirconium Zr702 Zr704 Zr705 Zirconium wire

Zirconium 702 is a commercially pure Zirconium. Zirconium is a reactive metal that has a high affinity for oxygen resulting inthe formation of a protective oxide layer in air at room temperature. This protective oxide gives Zirconium alloys their superior corrosion resistance. This oxide layer can be enhanced through a heat treating process. A properly formed enhanced oxide layer serves as an excellent bearing surface against a variety of materials, imparts impressive erosion resistance in high velocity systems and can improve the corrosion restance in certain aggressive environments.        

Zirconium alloys exhibit good ductility even at cryogenic temperatures and good strength comparable with 

other common engineering alloys.
