ASTM F30 / Nickel Alloy 52 / N52 / Niloy52 Low Expansion Alloy Wire

Product Description

NIFE 52 / ASTM F30 / Nilo 52 / 52H / N52 Fe-Ni constant expansion alloy Wire
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.
