Product Description

N14052 Alloy 52 sealing to glass in electronic applications

Alloy 52 is also known as N52 alloy. It is a FeNi alloy for glass-to-metal seals for some of the soft glasses and ceramics. It is intended primarily for sealing to glass in electronic applications but may be used for sealing to ceramics as well.


Chemical composition

Element Ni Mn Si C Cr P S Al Fe
wt, % 50.5 0.60 0.30 0.05 0.25 0.025 0.025 0.1 Rem

The nickel contents listed are nominal. The nickel contents of the alloys shall be adjusted by the manufacturer so that the alloys meet the requirements for thermal expansion. The 52 Alloy is specifically intended to match lead (Pb) sealing glasses




  • Good ductility
  • Near zero coefficient of linear thermal expansion
  • High strength and toughness at cryogenic temperatures



  • Electron gun components
  • Hermetic feedthroughs
  • Magnetic reed switches
  • Glass to metal seals that need controlled linear expansion
