Alloy 42 Sheet Nilo 42 (UNS K94100 /ASTM F30 / 1.3917)
Grade: 4J42|Nilo 42|FeNi42|K94100|Alloy 42
Alloy 42 variety specification and supply status: the variety includes bar, pipe, plate, strip and wire.
Alloy 42 smelting and casting process: smelting with non vacuum induction furnace, vacuum induction furnace or electric arc furnace.
Application and special requirements of alloy 42: Alloy 42 is a typical brand of glass sealing alloy, which has been used in aviation factory for a long time and has stable performance.
Alloy 42 is mainly used for sealing with soft glass, ceramics, etc. to make leads, frames and sealing plugs for electronic tubes, transistors and integrated circuits.
Heat treatment system of expansion coefficient performance test sample specified in alloy 42 heat treatment system standard: heat the sample to 900 ℃ ± 20 ℃ in hydrogen atmosphere for 1h, and cool it to below 200 ℃ at a speed of no more than 5 ℃ / min [4].

In 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 properties.
When forging and rolling materials are used, the air tightness of materials shall be strictly inspected
