Super Enamelled Constantan Wire for Wire Wound Resistor , Enamel
These enameled resistance wires have been broadly used for standard
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.
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
Also, it is the negative element of the type T thermocouple with
OFHC Copper the positive; type T thermocouples are used at
Constantan, CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19,
CuNi23, CuNi30, CuNi34, CuNi40 (6J40), CuNi44.
Constantan wire Characteristics
Constantan has a number of special characteristics due to which it
is known as the most versatile alloy that is available. Some of its
important characteristics are:
- High specific heat resistance
- Negligible temperature Coefficient
- Easily ductile
- Resistant to atmospheric corrosion
- Can be easily soldered and molded
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.
