Nickel Chromium Alloy Resistance Heating Wire 80% NICKEL - 20% CHROMIUM NI/CR-80/20 is the highest development in metallic alloys for use as resistors at elevated temperatures. Processes developed over the years led to steady increase in the ability of this alloy to withstand high temperatures for long duration NI/CR - 80/20 is essential for resistors elements in the higher temperature applications such as electric furnaces, electric ranges, radiant heaters operating at temperatures up to 2100 � F. In addition to these qualities and standard uses it has found wide application for resistance in technical applications due to its combination of high electrical resistance and a temperature much less than Nickel Chromium 60.  - Withstands Operating Temperatures To 2100�F
- Corrosion Resistant
- Long Life, Quick Heating
- Formed To Make Helical Coil Heaters
