Kovar Alloy Strip

KOVAR

Kovar alloy has a linear expansion coefficient similar to that of borosilicate hard glass at 20-450 ° C, a higher Curie point, and good low-temperature structural stability. The oxide film of the alloy is dense and can be well wetted by glass. And it does not interact with mercury, so it is suitable for use in instruments containing mercury discharge. It is the main sealing structure material of electric vacuum devices.
