Description

Precision Resistance Strip (CuNi40) Size 0.01mm * 100mm Use For Strain Gauge


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.
