Kovar(4J29) Alloy Material
Kovar/4J29/UNS K94610/W.Nr.1.3912

Kovar glass sealed and controlled expansion alloys
Equal grades: ASTM F15, Nilo-K,UNS K94610 (FeNi29Co17), 4J29, 29HК
Applications:
Kovar alloy has been used for making hermetic seals with the harder Pyrex glasses and ceramic materials
This alloy has found wide application in power tubes, microwave tubes, transistors and diodes. Integrated circuits, it has been used for the flat pack and the dual-in-line package
Our factory has over 15 years' experience of Kovar capillary production
Size range we could supply is:
