Alloy 52 Description


Alloy 52 was developed for glass-to-metal seals for some of the soft glasses and ceramics. The alloy’s rate of thermal expansion is virtually constant to a temperature of about 1050°F (565°C).

Applications


Magnetic reed switches
Glass to metal seals that need controlled linear expansion

Properties Tempered


Alloy 52 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.

Additional Properties

Corrosion Resistance


Refer to NACE (National Association of Corrosion Engineers) for recommendations.

Standard Wire Finishes


Extra Clean: (XC) Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”
Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications
Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation. A soap finish is available in tempered products.
Plated: Many plating options are available.
∗Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.
