OD1.0 mm Glass Sealing 52 Alloy Capillary Tube Used for Glass Sealing
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.
