For High Integrity Glass and Ceramic To Metal Seals
A Nickel-Iron-Cobalt, controlled expansion alloy containing 29% Nickel. It's 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. Looking forward to co-operating with you!
