4j29 Kovar alloy Strip Cold Rolled Kovar Strip Full Annealed

(Common Name: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)

It is also known as Kovar alloy.Kovar Strip was invented to meet the need for a reliable glass-to-metal seal, which is required in electronic devices such as light bulbs, vacuum tubes, cathode ray tubes, and in vacuum systems in chemistry and other scientific research. Most metals cannot seal to glass because their coefficient of thermal expansion is not the same as glass, so as the joint cools after fabrication the stresses due to the differential expansion rates of the glass and metal cause the joint to crack.
