Product Details

MATERIAL OVERVIEW

Characteristics: 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.  Kovar finds 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.
