Zirconium Wire

Finished zirconium wire is produced by cold drawn technology. Before the last drawing process, zirconium rods have to be properly heated and reduced from bigger to smaller diameter step by step. Zirconium wire usually is in annealed condition and the final annealing temperature and time will significantly have influence on wires’ hardness and ductibility. Zirconium wires are commonly used in chemical, aerospace, medical, nuclear, entertainment, jewelry and many other niche applications.  

HEXON supply the major industrial grades of zirconium, including Zr702 (R60702), Zr704 (R60704) and Zr705 (R60705). We adhere to ASTM B551 for industrial and AWS A5.24 for welding application. Besides normal purity we are also capable of providing higher purity zirconium wire with Hafnium content less than 1%.

No matter for small piece or large size, quality always means the same thing to HEXON. For instance, we analyze the VAR ingot, take specimen from finished product for tension test, and inspect each rod by Ultrasonic to prevent potential internal defects. Starting process from ingot also makes our price very competitive in the market.

HEXON provide EN 10204/3.1 certification including related tests and inspections stipulated in ASTM. If necessary, HEXON also can provide certification to report the grain-size which is examined by SEM.
