Features


4J29 alloy has a coefficient of expansion similar to that of hard glass in a wide temperature range (-80~450 °C). In the electric vacuum industry, it is used to seal high-viscous components with hard glass. Ceramic sealing. Name: Iron nickel cobalt glass sealing alloy. It has a thermal expansion coefficient similar to that of silicon-boron hard glass at 20~450 °C, and has a high Curie point and good low temperature structure stability. It is an iron nickel cobalt glass sealing alloy.
