4J29 alloy is also known as Kovar alloy. The alloy has similar linear expansion coefficient, higher Curie point, and good microstructure stability at low temperature to that of borosilicate hard glass at 20~450℃. 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 meters. It is the main sealing structure material of electric vacuum device.
