Kovar® Alloy (Glass and Ceramic Sealing Alloy)
Subcategory: Superalloy; Electronic/Magnetic Alloy
Key Words: UNS K94610; ASTM F15, 29-17 alloy
Material Notes: Iron content calculated as remainder. Data provided by Carpenter Technology Corporation. Kovar® alloy is a vacuum melted, Fe-Ni-Co, low expansion alloy whose chemical composition is controlled within narrow limits to assure precise uniform thermal expansion properties. Kovar alloy has been used for making hermetic seals with the harder Pyrex glasses and ceramic materials. This alloy has found wide application in power tubes, microwave tubes, transistors, and diodes. In integrated circuits, it has been used for the flat pack and the dual-in-line package.
