What are the applications?
Resistance wires are manufactured from nickel alloys which have specialist properties such as electrical resistance, oxidation resistance, strength and corrosion resistance – all at elevated temperatures.
Resistance wire is thus used primarily in resistance heating elements, hot wire cutting, heat sealing, resistors and springs and fasteners for high technology industries. It is also used extensively as a glass sealing element.

Corrosion Resistance
Refer to NACE (National Association of Corrosion Engineers) for
recommendations.
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 for custom finishes
Heat Treatment
Alloy 80/20 is non hardenable by heat treatment.
