Nickel Base Alloy Tube Invar 42 4j42 Tube Sealing Aircraft Vacuum Instruments

 

Alloy-4J42 (Expansion alloy)
(Common Name: 42H Glass Sealing 42, Nilo42, N42, FeNi42)

4j42 Tube is mainly composed of iron, nickel elements. It is characterized with a fixed coefficient of expansion. Increase the thermal expansion coefficient and the Curie point with increase of nickel content.
4J42 alloy is widely used the structure of the sealing material in the electric vacuum industry.
