Application of Constantan
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.
