Description

Precision Alloy ASTM F15 4J29 Kovar Alloy Round Bar And Rod
ASTM F15 4J29(Kovar) , 4J32,4J33,4J34,4J36(Invar) Kovar Bar


Kovar Alloy Round Bar 4j29 is a iron-nickel-cobalt, low expansion alloy whose chemical composition is controlled within narrow limits to assure precise uniform thermal expansion properties.


Kovar Alloy Round Bar alloy has been used for making hermetic seals with the harder Pyrex glasses and ceramic materials.
Kovar has been used to make hermetic seals with harder Pyrex and ceramic materials. In integrated circuits, it is used in planar packages and dual in-line packages. This alloy has a wide range of applications in power tubes, microwave tubes, transistors and diodes.
