Cuprothal 49 is an austenitic copper-nickel alloy (CuNi alloy) for use at temperatures up to 600°C (1110°F). The alloy is characterized by high electrical resistance, high ductility and good corrosion resistance.
In finer sizes the alloy's negligible temperature coefficient of resistance combined with its high resistivity makes it useful for the winding of precision resistors which must not change in resistance over a limited range in temperature. For this purpose the alloy is identified as Cuprothal 49 TC.
