Product Description
These enameled resistance wires have been broadly used for standard resistors, automobile
parts, winding resistors, etc. using the insulation processing best suited for these applications, taking full advantage of the distinctive features of enamel coating.
Furthermore, we will carry out enamel coating insulation of precious metal wire such as silver and platinum wire upon order. Please make use of this production-on-order.
Constantan Definition
Resistance alloy with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature
curve over a wider range than the "manganins". Constantan also shows better corrosion resistance than the man ganins. Uses tend to be restricted to ac circuits. Constantan is also the negative element of the type J thermocouple
with Iron being the positive; type J thermocouples are used in heat treating applications. Also, it is the negative element
of the type T thermocouple with OFHC Copper the positive; type T thermocouples are used at cryogenic temperatures.
Constantan material:
Constantan, CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi40 (6J40), CuNi44.
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 f or 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.
