4J29 Kovar iron-nickel-cobalt alloy heating wire








Kovar is an iron-nickel-cobalt alloy with a coefficient of thermal expansion similar






to that of hard (borosilicate) glass. This makes it especially suitable for uses which






require a matched-expansion seal between metal and glass parts.






Thus kovar finds wide usage in the electronics industry for metal parts bonded to hard






glass envelopes for such devices as power tubes, x-ray tubes, etc, and other






applications requiring glass-to-metal seals.
