Niobium - Zirconium / Wire
Description
Niobium-Zirconium (Nb-Zr) alloys refer to the alloys composed of zirconium added to metal niobium, and it is regarded as a low-strength alloy. The alloys in general are inconvenient to weld. Both sides of the weld must be protected with a stream of inert gas, because hot niobium will react with oxygen and nitrogen in the air. The addition of 1% zirconium to niobium greatly improves the creep strength over the soft pure metal. Thus, Nb99Zr1 can replace pure niobium in applications requiring the chemical resistance of niobium and a material with high melting temperature.
Alfa Chemistry provides high-quality niobium-zirconium Wires which is worked from ingot to final diameter, furnished in coils or on spools or reels at a competitive price, which can be used in the welding industry or nuclear industry, and so on.

Applications
In addition to greatly increasing the strength of pure niobium at higher temperatures, Nb99Zr1 also has low thermal nuclear capture cross-section properties. Furthermore, Nb99Zr1 has the advantage of being less expensive than the higher strength alloys. It can be used in applications where a high temperature material is needed with low loads. Its application areas can be summarized as follows:
- Nuclear industry
- Chemical industry
- Aviation and aerospace
- Mechanical manufacture
