ISOTAN® thermocouple alloy is a versatile Copper-Nickel alloy (CuNi44Mn1), offering a low-temperature coefficient and high resistance to oxidation and chemical corrosion. While it can be used for electrical resistors and potentiometers, it is not suitable for precision components due to its high EMF compared to Copper. ISOTAN® can be supplied in a wide range of grades, qualities and versions depending on the application and customer’s requirements (such as custom standardised temperature range). Most commonly it is used as a negative leg of thermocouple types J, L, T, U or E, extension and compensation leads. ISOTAN® is available in form of round wires from 0.03 to 10mm² which can be bare or enamelled (between 0.05-1.5mm²), flat wire, ribbons or rods.

Please see the datasheet for an outline guide of properties.
