Alloy 42 Tube

Alloy 42 tube 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).

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.
