Alloy resistors mainly play a role in current detection in circuits, therefore they are also known as sampling resistors or current detection resistors. The main materials of alloy resistors include manganese copper alloy, nickel copper alloy, nickel chromium alloy, iron chromium aluminum alloy, constantan alloy, and kama alloy, among others. The resistance characteristics and resistivity of various alloy materials are different. Below, we will explain the resistance selection parameters of Suzhou Walter alloy.
