Application
4J29 is mainly used for electric vacuum components such as emission tubes, oscillator tubes, ignition tubes, magnetrons, transistors, sealed plugs, relays, integrated circuits, lead wires, chassis, shells, brackets, etc., glass sealing, in the application of the glass should be made to select the coefficient of expansion of the alloy and alloy match, according to the temperature of the use of the low-temperature organisational stability of the strict test, the processing should be carried out in an appropriate heat treatment to ensure that the material has a good deep-drawn elongation. The material has good deep-drawn performance, when the use of forging material should be rigorously tested for airtightness.
4J32 is suitable for a variety of instruments, instrumentation parts, thermal bimetallic passive layer and resonance cavities that require dimensional stability.
