Kovar alloy tube , Alloy K / UNS K94610 / ASTM F15
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.
Main Application:
Matching sealing in electric vacuum industry and hard glass

The linear expansion coefficient of the kovar alloy is similar to that of borosilicate glass at 20-450 ℃, the Curie point is higher, and the alloy has good low temperature structure stability. The oxide film of the alloy is compact and can be well infiltrated by glass. It does not interact with mercury and is suitable for use in instruments containing mercury discharge. It is the main sealing structure material of electric vacuum device.
