constantan
Sign in to saveAlso known as Eureka, Advance, Ferry
Constantan refers to a copper-nickel alloy commonly used for its stable electrical resistance across a wide range of temperatures. Alternatively it is known in various contexts as Eureka, Advance, or Ferry. It usually consists of 55% copper and 45% nickel. Its main feature is the low thermal variation of its resistivity, which is constant over a wide range of temperatures. Other alloys with similarly low temperature coefficients are known, such as manganin (Cu [86%] / Mn [12%] / Ni [2%] ).

Le constantan est un alliage métallique constitué principalement de cuivre et de nickel, de l'ordre de 60 % à 50 % cuivre et 40 % à 50 % en masse de nickel ; donc similaire au cupronickel mais avec plus de nickel. Son intérêt provient de la stabilité en température de sa résistivité.
