Product Description

4J42
Uses: Used to make iron-nickel alloy strips, rods, pipes, wires and plates that are matched and sealed with soft glass and ceramics on electrical components. In the electric vacuum industry, it is matched and sealed with the corresponding soft glass.

Alloys are mainly used for sealing with soft glass, ceramics, etc., and making leads, frames and sealing plugs of electron tubes, transistors and integrated circuits. In the application, the selected sealing material should match the expansion coefficient of the alloy. The grain size should be controlled during heat treatment to ensure that the material has good deep drawing and drawing properties. When using forged and rolled materials, the air tightness of the materials should be strictly inspected.

4J42 heat treatment system
The heat treatment system of the test sample for the expansion coefficient performance specified in the standard: heat the sample to 900°C ± 20°C in a hydrogen atmosphere, keep it for 1 hour, and cool it to below 200°C at a speed of no more than 5°C/min.
