Constantan Alloy

A copper-nickel alloy that contains minor amounts of additional elements, in this case, manganese, and iron, to achieve precise values for the temperature coefficient of resistivity for strain gauges. This alloy employs an adequately high strain sensitivity or gauge factor. Its resistivity is high enough to achieve suitable resistance values in very small grids, and its temperature coefficient of resistance is not excessive while having good fatigue life and relatively high elongation capability.

Chemical Composition: Cu= 53.8% Ni= 44.2%, Mn= 1.5%, Fe= 0.5%
Typical Applications

Constantan alloys are used in foil resistors and strain gauges

Packaging Options



Metals; Inorganic; nanomaterials
