Introducing our Constantan Wire CuNi44, a premium resistance alloy wire designed for precision applications. Composed of 55% copper, 44% nickel, and 1% manganese, this wire boasts a very low temperature coefficient of resistance, with a TCR of less than ±40 ppm/°C. It's perfect for creating high-accuracy wirewound resistors and thermocouple extension leads, as well as for low-drift current sensing.

Available in diameters ranging from 0.05mm to 2.0mm, our Constantan wire can be supplied on spools or in straightened lengths. Not only does it offer excellent solderability, but it also ensures long-term stability, making it the ideal choice for your precision needs. Elevate your projects with the reliability and performance of CuNi44 resistance alloy wire!
