Kovar Parts Machining:

Kovar alloy is a vacuum melted, iron-nickel-cobalt, low expansion alloy whose chemical composition is controlled within narrow limits to assure precise uniform thermal expansion properties. Extensive quality controls are employed in the manufacture of this alloy to ensure uniform physical and mechanical properties for ease in deep drawing, stamping and machining.We has the experience, knowledge, and CNC equipment required to machine a wide array of materials, including Kovar. Our custom design and manufacturing services means you receive a unique solution to your complex component problems.


Kovar, also known as ASTM F 15 Alloy, is a controlled expansion alloy that is typically applied to high integrity glass and ceramic to metal seals, lids, lead frames and electronic package base.  Widely used in the hermetic seal industry.  We specialize in machining kovar.An iron-nickel-cobalt ferrous alloy that has a thermal expansion similar to glass which makes it reliable for glass-to-metal seal applications. Kovar bonds to glass through the intermediate oxide layer of nickel (II) oxide and cobalt (II) oxide. Kovar has application in power tubes, microwave tubes, transistors and diodes, and integrated circuits.
