0.02mm Constantan/ CuNi44Mn1/ Konstantan Metal Foil/ Strip for Electric Elements

 

Constantan is a nickel copper based alloy wire that has a high resistivity and is mainly used for thermocouples and electrical resistance heating. It has a constant resistivity over aa wide range of temperature.

 

Constantan Wire Resistance

The resistance of constantan wire is 15.94 ohm-cmil/ft. Since the resistance of constantan does not change with temperature, it is used for the purpose of making thermocouples and other such appliances where the resistance should remain constant for a particular range of temperature. It is an electric resistance wire.

Uses of Constantan

Constantan is used for the measurement of temperature. It is used for the formation of thermocouple, along with the wires of other metals such as copper, iron and chromel. It is especially used for resistance purpose since its resistance does not change much with the change in its temperature. It is used for DC current shunts. In the DC current shunts, the precision low value resistance wire is placed in series with the load in a direct current circuit, which is already carrying a high current. It one measures the voltage drop; he can easily measure the current.

Constantan Alloy

Constantan is one of the most widely used alloys. This is owing to the fact that it has the best overall composition of the important properties that is needed for many of the strange gauge applications. Constantan has the highest resistivity among all the other alloys, which makes it insensitive to the level of strain and temperature. Its resistivity is so high that it can also achieve suitable resistance levels in very small grids also. The temperature coefficient of resistance is not at all excessive in case of constantan alloy. Therefore it has very many advantages over the other alloys.

Constantan has a good fatigue life and a very high elongation capacity also. All these additional properties make it a highly useful and good alloy. But this alloy shows drift at the temperature range of 65 °C, therefore this point should be kept n mind when one tests the stability strain if the gauge, since its stability strain is critical at this temperature.
