Kovar alloy has been used for making hermetic seals with the harder Pyrex glasses and ceramic materials.
Glass sealed and controllled expansion alloys
*kovar alloy, ASTM F15, Nilo- K, UNS K94610 (FeNi29Co17) , Chinese 4J29
*ASTM F15; DIN 17745; S. E. W. 385; Werkstoff Nr. 1. 3981; AFNOR NF A54- 301
Note:
A Nickel- Iron- Cobalt, controlled expansion alloy containing 29% Nickel. Its coefficient of expansion (which decreases with rising temperature to the inflection point) , matches the expansion rate of borosilicate glasses and aluminia ceramics. Applications include glass to metal seals in applications requiring high reliability or resistance to thermal shock, ie. high- power transmitting valves, transistor leads and heaters and photography flash bulbs.
