Special Offer Constantan Wire CuNi44 Copper Nickel Alloy Wire Used
in Fine Gaugesc
Introduction
Constantan Wire 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 wire 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 Wire for Sampling Resistor is a copper-nickel alloy
usually consisting of 55% Copper and 45% Nickel. Its main feature
is its resistance which is constant over a wide range of
temperatures. It is also called Alloy 294, Nico, MWS-294, Cupron,
Copel, Alloy 45, Neutrology, Advance, CuNi 44, CuNi 44, CN49.
Applications
It is suilable for electrical resistors, potentiometers, heating
wires, heating cables and underground heating mesh; braiding and
shielding in flexible coaxial cable and communication cable, a
variety of
audio and video cable, vehicle signal cable, network cable, data
transmission cables ang so on.
