CuNi10 Copper Nickel Alloy Wire Stable Resistivity Low TCR Corrosion Resistant Non-magnetic Resistance Wire for Electronic Components Thermocouple Heating Parts
CuNi10 is a widely applied copper-nickel resistance alloy with stable electrical performance and low temperature coefficient of resistance. It features good corrosion resistance and oxidation resistance, performing steadily under common working conditions. This non-magnetic material has excellent ductility and is easy to cut, bend and weld. Available in wire, strip and other forms, it is commonly made into resistance components, thermocouples and heating parts, and widely used in electronic instruments, electrical appliances and automatic control systems.
