Constantan Wire CuNi44 / 2.0842 0.15mm 0.35mm Bare Wire For Heating Elements
Common names: CuNi44 / 2.0842/MWS-294
Wire range: 0.05~8mm
Product Description
Copper nickel alloy Wire with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature curve over a wider range than the "manganins". it also shows better corrosion resistance, and welding performance.
The copper-based low resistance heating alloy is widely used in
low-voltage circuit breaker, thermal overload relay, and other
low-voltage electrical product. It is one of the key materials of
the low-voltage electrical products. The materials produced by our
company have the characteristics of good resistance consistency and
superior stability. We can supply all kinds of round wire, flat and
sheet materials.
DIN spools are available for the package as per your requests.
Stranded or bunch wires are available if you need.
Enamelled wire can be tailor-made.
