constantaan
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%] ).

Constantaan is een legering van koper (54%), nikkel (45%) en mangaan (1%). De elektrische weerstand van deze legering blijft redelijk constant over een groot temperatuurbereik. De legering werd ontwikkeld door Edward Weston, en wordt gebruikt voor ijkweerstanden, in meettoestellen, thermokoppels en overal waar de weerstandswaarde zo constant mogelijk moet blijven.
