ASTM F15 Iron Nickel Cobalt Kovar alloy 4J29 strip in coils

Glass sealed and controlled expansion Kovar alloys
* kovar alloy, ASTM F15, Nilo-K, UNS K94610 (FeNi29Co17), Chinese 4J29
*Specifications:ASTM F15; DIN 17745; S.E.W. 385; Werkstoff Nr. 1.3981; AFNOR NF A54-301

Kovar Alloy, also know as ASTM F-15, NILO K, Pernifer 2918, Rodar, and Dilvar P1 is 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.
