4j52/Pernifer 50 Glass Sealing 52 Alloy Tube

Short Description:

NIFE 52 / FENI52 / Nilo 52 / UNS / UNS N14052 Fe-Ni sealing alloy Tube

Alloy 52 Contains 52% nickel and 48% iron and is widely used in the telecommunications industry.It also finds a application in a wide variety of electronic applications,especially for glass seals.

Alloy 52 is one of the glass to metal sealing alloys designed for use with a variety of soft glasses. Known for a coefficient of thermal expansion that is almost constant up to 1050F (565 C).

     Forming:
    The alloy has good ductility and can be formed by standard means.
    Welding:
    Welding by conventional methods is appropriate for this alloy.
    Heat Treatment:
    Alloy 52 should be annealed at 1500F followed by air cooling. Intermediate strain relieving can be performed at 1000F.
    Forging:
    Forging should be done at a temperature of 2150 F.
    Cold Working:
    The alloy is readily cold worked. Deep drawing grade should be specified for that forming operation and annealed grade for general forming.
