1 PRODUCT

Alloy 80/20 Nickel Chromium, UNS N06003, W.Nr. 2.4869 sheet, strip, foil, wire(round, flat, square, profile) for electrical heating elements.

2 APPLICATION

Alloy 80/20 Nickel Chromium is used for electrical heating elements for industrial devices such as flat irons, water heaters, plastic moulding dies, soldering irons.

Alloy 80/20 wire is commonly used as a resistor at elevated temperatures. Alloy 80/20 is essential for resistor elements in high temperature applications such as electric furnaces, electric ranges and radiant heaters operating at temperatures up to 1150°C (2100°F).

In addition to these qualities and standard uses, it has found wide application in technical applications due to its combination of high electrical resistance and its temperature coefficient of resistance much less than that of Nickel-Chrome 60.

3 OVERVIEW

Alloy 80/20 Nickel Chromium is a resistance heating alloy comprised of 80% Nickel and 20% Chromium.

Alloy 80/20 Nickel Chromium can be used at operating temperatures up to 1200°C (2190°F). Its chemical composition gives good oxidation resistance especially under conditions of frequent switching or wide temperature fluctuations.

8 SHEET, STRIP, FOIL 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 us for Applicable Finishes.

9 WIRE FINISHES

XC - Extra Clean Bright Annealed or Bright Annealed and Cold Rolled Grease - Ultra bright finish (for decorative applications)

Soap - Soap coating on tempered wire to act as lubricant
