Product Description

Constantan is a copper-nickel alloy usually consisting of 55% copper and 45% nickel, also known as Eureka,
Advance and Ferry. Its main feature is its resistivity which is constant over a wide range of temperatures. Other alloys with similarly low temperature coefficients are known, such as manganin.
Its resistivity is high enough to achieve suitable resistance values in even very small grids, and its temperature
coefficient of resistance is not excessive. In addition, constantan is characterized by good fatigue life and relatively high elongation capability.
