Invar 32 Wire - Super Invar 32-5 - ASTM F1684 - UNS-K-93500

Super-Invar32-5 Wire

Consisting of 32% Nickel, 5% Cobalt, and the balance Iron, this alloy exhibits minimum thermal expansion (one half of Invar 36) at room temperature. It is often used in structural components, supports and substrates requiring precision measurements

Applications

Optical and laser systems

Telescopes

Laser bench tops

Ring laser gyroscopes

 

Main features:

Low expansion coefficient in the range of 20-100 ° C
