Alloy30 Solid Wire 0.25mm On DIN125 Spool Used For Automobile Cables Heating Cables
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.
