Precision Resistance Strip (CuNi40) Size 0.01mm * 100mm Use For
2. Product Description
Constantan 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.
