About This Product
Constantan is a nickel-copper alloy used for resistance wire because its resistance changes very little as the temperature rises. In school physics it is wound into resistance coils and used in rheostats and bridge-wire experiments, where steady resistance gives reliable readings. The SWG number shows the thickness, and a lower number means a thicker wire. School Lab Equipment India can export the Constantan Wire, Roll of 75 grams to education buyers in South Sudan, Seychelles, Côte d'Ivoire, Slovenia, Colombia and Guinea-Bissau.
