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.
