Description
Nilo42 FeNi Glass Sealing Kovar Alloy FeNi42 Strip For Glass Sealed Making Material

Nilo42 FeNi Glass Sealing alloy strip FeNi42 strip Used for glass sealed material making electron tubes, transistors

 

​Nilo42 alloy 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.
​Nilo42 alloy is widely used the structure of the sealing material in the electric vacuum industry.
