Kovar 4J29 Bars is also known as Kovar alloy. The alloy has a linear expansion coefficient similar to that of borosilicate hard glass at 20 ~ 450℃, a higher Curie point, and a good low temperature microstructure stability. The oxide film of the alloy is dense and can be well infiltrated by glass. And does not interact with mercury, suitable for use in mercury discharge instrument. It is the main sealing structure material of electric vacuum device.
