NIC80 wire is commonly used as a resistor at elevated temperatures. NI/CR-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. ## **Specifications** **Composition:** 80% Ni, 20% Cr **Specific Resistance:** 650 Ω per circular mil-foot at 20°C (68°F). See table below for multiplication factors to obtain resistance at other temperatures. **Specific Gravity:** 8.41 **Density:** 0.304 lb/in[3] **Shown smaller than actual size.** **Melting Point:** Approx 1400°C (2550°F) **Nominal Coefficient of Linear Expansion:** 0.000017 (10 to 1000°C) **Tensile Strength (lb/in[2] ) at 20°C (68°F): Soft Annealed:** 100,000 **Nominal Temperature Coefficient of Resistance:** 0.00011 Ω/Ω/°C (20 to 500°C) |**Factor by Which Resistance at Room Temperature Is to Be Multiplied to Obtain Resistance at Indicated Temperatures**
