What is Constantan?
Constantan is an alloy composed of two elements: copper and nickel It is also known as Cupronickel and is often used in various electrical and thermal applications. Constantan has a wide range of applications because of its unique properties. It has a low electrical resistance that increases very slightly with temperature. At the same time, its thermal conductivity is low but increases gradually over temperature. It also has low magnetic properties, making it suitable for applications where magnetic fields need to be excluded.
Constantan is most commonly used for electrical resistance thermometers, thermocouples, and resistance strain gauges. These components are designed to measure temperature or strain in a variety of settings. Constantan is also used for heating elements, such as those found in hair dryers, toasters, and electric grills. Its combination of low resistivity and temperature dependence makes it perfect for these applications. In addition, Constantan is used in electrical engineering and electronics, in particular for resistors and precision electrical cable.
