Constantan Wire 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". CuNi44 Alloy wire also shows better corrosion resistance than the man ganins. Uses tend to be restricted to ac circuits. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy 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.
| roduct Name | Copper Nickel Alloy CuNi Wire |
| Product Description | Copper Nickel Alloy is mainly made of copper and nickel. The copper and nickel can be melted together no matter what percentage. Normally the resistivity of CuNi alloy will be higher if the Nickel content is larger than Copper content. From CuNi6 to CuNi44, the resistivity is from 0.1μΩm to 0.49μΩm. That will help the resistor manufacture choosing the most suitable alloy wire. |
| Product Features | By the way, the Copper Nickel wire is easy to be welded and easy to be fabricated, so it can be made into many forms and widely used in all areas. |
