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
