Iron Nickel Alloy 42 Tube Sealing Structure Material For Electric Vacuum Industry

Alloy 42 Tube Ni42 Fe42Ni (UNS K94100 /ASTM F30) expansion alloy

Alloy42 tube is an iron nickel constant expansion alloy. It is a series of constant expansion alloys that can match soft glass and ceramics with different expansion coefficients in a given temperature range by adjusting nickel content. Its expansion coefficient and Curie point increase with the increase of nickel content. The alloy is a widely used sealing structure material in the electric vacuum industry.

  • Description

Alloy 42 belong to a controlled expansion alloy Similar called: 4J42, Nio 42, NI42 Fe42Ni (UNS K94100 /ASTM F30) (aka Pernifer 402, NILO 424, Glass Seal 421).

Characteristics: The expansion coefficient is matched with the material to be sealed, and the plasticity is good. Easy to process, no phase change occurs in the working temperature range, good electrical conductivity, thermal conductivity, and high mechanical strength and good processability. The fixed expansion alloys used for sealing include Fe-Ni, Fe-Ni-Co, Fe-Ni-Cr, Ni-Co, as well as oxygen-free copper, tungsten, molybdenum and alloys thereof, composite materials and the like.
