Product Description
HUONA CuNi44 (CuNi40 CuNi45 CuNi44) Heating Resistance Alloy Rod
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.Chemical Content

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
