The Resistivity of Constantan Wire is slightly hyper than Manganin Resistivity, the curve between resistance and temperature is a linear relationship. The Alloy is limited to make precise resistance, sliding resistance, adjustable rehostat and resistance strain gage which is working below 200 degrees Celsius as it has higher copper thermoelectric emfs. Which also can be used as electric heating element works below 100degrees Celsius.
We have all kinds of Wire Gauge/Length of Nichrome Wire, Alchrome Wire and FeCrAl wire, please kindly have a check in our store or contact our customer service for more details.
