CuNi44 Copper Nickel Resistance Wire with Low Temperature Coefficient for Precision Resistors and Excellent Corrosion Resistance

Product Description

CuNi44 Copper Nickel Resistance Wire (Constantan Alloy) for Precision Resistors

CuNi44 alloy (also known as Constantan, Alloy 300, Cuprothal 294, Cupron) is a copper-nickel resistance alloy with 44% nickel content. It features an extremely low temperature coefficient of resistance (TCR), making it ideally suited for precision resistors, shunts, thermocouple extension wires, and low-temperature heating applications.

Our CuNi44 wire offers excellent resistance consistency, good weldability, and long-term stability. It is widely used in electrical instruments, automotive sensors, aerospace control systems, and laboratory equipment.

We can supply round wire, flat wire, and ribbon/strip in various diameters and tolerances
