Product Description
Kovar is made up of 29% nickel, 17% cobalt, .2% silicon, .3% manganese and 53.5% iron. Kovar? is known for its low coefficient of thermal expansion. Kovar end uses are usually glass sealing in the electronics industry.
Kovar Sheet
Alloy K / K94610 / ASTM F15 Also known as Kovar and Nilo K**, this alloy contains 29% nickel with a 17% cobalt addition. Its composition is tightly controlled within narrow limits to ensure precise and universal thermal expansion and mechanical characteristics. This helps the material provide high integrity glass-to-metal and ceramic-to-metal seals in applications requiring reliability and resistance to thermal shock. Alloy K is often used for the manufacture of hermetic seals with both the harder Pyrex or borosilicate glasses and alumina-type ceramic materials. It finds extensive application in the production of transistors and diodes for lids and closures in a variety of hybrid electronic circuit packages and also in the manufacture of microwave tubes.
