Kovar Round Bars, AMS 7727, ASTM F15, UNS K94610, 1.3981

Description

Kovar Round Bars / AMS 7727 / ASTM F15 / 1.3981 / UNS K94610 Round Bars

Kovar Round Bars is a Iron Nickel Cobalt, low expansion alloy whose chemical composition is controlled within narrow limits to assure precise uniform thermal expansion properties. A glass and ceramic sealing alloy, extensive quality controls are employed in its manufacture to ensure uniform physical and mechanical properties for ease in deep drawing, stamping and machining.

Kovar (Alloy K) is 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 alumina ceramics. Kovar (Alloy K) is used for glass-to-metal seals in applications requiring high reliability or resistance to thermal shock. Kovar (Alloy K) is used for high-power transmitting valves, transistor leads and headers, integrated-circuit lead frames, and photography flash bulbs.
