Nb1Zr and pure niobium have very similar physical properties. Alloying niobium with 1% zirconium increases the strength of niobium, and decreases slightly its elongation. The increased strength is very advantageous especially at temperatures above 600 °C.

Advantages compared to pure Nb:

• higher strength
• lower embrittlement in contact with gases

Typical areas of application:

• lamp components for special lighting applications
