Cuprothal 294 Copper Nickel Alloy Wire 0.08mm for Precision Instrument

Product Description
Constantan and Manganin is a copper-nickel alloy that contains specific minor amounts of additional elements to achieve precise values for the temperature coefficient of resistivity. Careful control of melting and conversion practices results in a very low level of pinholes at ultra-thin thicknesses. The alloy is used extensively for foil resistors and strain gauges.
