Applications

Applications for Alloy 52 include magnetic reed switches and seals that need controlled linear expansion to approximately 977°F (525 °C)

Description

Alloy 52 is a 50.50% nickel-iron alloy developed for glass-to-metal seals for some of the soft glasses and some ceramics. The alloy’s rate of thermal expansion is virtually constant to a temperature of about 1050°F (565°C).

Finishes
#1 – Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required. # 2D – Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process. # 2B –Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D. #BA Bright annealed cold rolled and bright annealed #CBA Course bright annealed cold rolled matte finish and bright anneal #2 Cold Rolled # 2BA – Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part. Polished – Various grit finish for specific polish finished requirements
* Not All Finishes are Available for All Alloys – Consult Sales for Applicable Finishes
Wire Finishes
XC-Extra clean. Bright annealed or bright annealed and cold rolled
Grease-Ultra bright finish for decorative applications
Soap-Soap is not removed from tempered wire to act as a lubricant.
* Contact Ulbrich Wire with special finish requests.
Heat Treatment Alloy 52 is non hardenable by heat treatment.
Welding For best results refer to: SSINA’s “Welding of Stainless Steels and Other Joining Methods”.
