Niobium Zirconium Rod
Product Niobium Zirconium Rod (NbZr Rod)
Part Number TRM-NB009
Standard ASTM B392
Material UNS R04261
Density 8.57 g/cm3

Niobium-1% zirconium alloy is used in the nuclear industry. It is regarded as a low-strength alloy. In addition, niobium alloys in general are inconvenient to weld, that is to say, both sides of the weld must be protected with a stream of inert gas, because niobium will react with oxygen and nitrogen in the air. Niobium-1% zirconium rod (NbZr Rod) is worked from the ingot to the final diameter.

Application: The niobium zirconium rods (NbZr Rod) are used in the fabrication of corrosion-resistant equipment and in the nuclear industries, and etc.

Thermostability 85%
Machinability 78%
Corrosion Resistance 83%
