Nichrome Bare Wire 20 Swg
Product Code : JA-EE-7625
Nichrome Bare Wire 20 Swg (SKU JA-EE-7625) is bare nichrome (nickel-chromium) wire of 0.90 mm diameter, nearest 20 SWG, supplied at 125 g. Nichrome has a much higher resistivity than copper and withstands being run hot, so a 20 SWG length makes a practical heating coil for Joule heating and calorimetry work as well as a sample for resistance comparisons. JaincoLab supplies this 20 SWG nichrome wire to school and college physics laboratories.
