Product Description and Application
4J29 is a typical Fe-Ni-Co hard glass sealing alloy, long-term use by the aviation plant, stable performance. The oxide film of the alloy is dense and can be well infiltrated by glass. It is the main sealing structural material for electric vacuum devices. It is mainly used for electric vacuum components such as emission tubes, oscillation tubes, ignition tubes, magnetrons, transistors, sealed plugs, relays, glass sealing of integrated circuit leads, chassis, shells, brackets, etc.
