Kovar, also known as Alloy V29-17, UNS K94610, DIN 1.3981, ASTM F-15, A54-301, and NILO K, is a nickel-cobalt-iron alloy known for its low coefficient of thermal expansion and its compatibility with glass and ceramics. These properties make it ideal for applications requiring a stable seal between metal and glass or ceramics, often used in electronic and electrical applications. Kovar is composed of approximately 29% cobalt, 17% nickel, and the remainder iron. This specific composition ensures minimal thermal expansion and makes Kovar suitable for applications where dimensional stability and thermal compatibility are essential. Available in flexible strips and coils, Kovar is used for applications where materials need to be bent, formed, or used continuously. These forms are valuable in the production of electrical contacts, connectors, and other components where flexibility and dimensional stability are critical.
