Alloy 52 0.25mm*0.64mm Precision Alloy Flat Wire/ Ribbon Wire
General Information:
Applications for Alloy 52 include magnetic reed switches and seals that need controlled linear expansion to approximately 977 °F (525 °C).
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).

Alloy 52 can be cold worked to various tempers. Contact Ulbrich Technical Service for additional information.
Refer to NACE (National Associate of Corrosion Engineers) for recommendations.
#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.
