Nilo 52 / Alloy 52 Expansion Iron -Nickel Alloy Strip

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.
