Nichrome NiCr 80/20 Heating Resistance Foil Strip For Loadbank Resistor
Nickel chromium strip is an important resistance alloy material, with commonly used grades including NiCr80/20 and NiCr70/30. Among them, NiCr80/20 represents the proportion of nickel and chromium in the alloy as 80% and 20%, respectively, while NiCr70/30 represents the proportion of nickel and chromium as 70% and 30%. These nickel chromium strips typically have excellent high-temperature resistance and stable resistance characteristics. Typical parameters include widths ranging from 0.2 millimeters to 5 millimeters and thicknesses ranging from 0.02 millimeters to 0.5 millimeters, which can be customized according to specific needs. These strips are widely used in industrial heating equipment, electric heaters, thermocouples, and other applications that require stable resistance, providing reliable solutions for various heating and temperature measurement needs.
