Alloy 45 / mws-294 / constantan Flat Wire Used For TN Thermocouple wire / Relay
Product Description
The constantan resistivity (4.9 x 10−7 Ω·m) is high enough to achieve suitable resistance values in even very small grids, and its temperature coefficient of resistance is fairly low.
This alloy has, for example, an adequately high strain sensitivity, or gauge factor, which is relatively insensitive to strain level and temperature.
Constantan is a proprietary name for a copper–nickel alloy also known as Eureka, Advance, and 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%] ).
Copper nickel alloy Wire with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature curve over a wider range than the "manganins". it also shows better corrosion resistance, and welding performance. It always used for thermal overload relay, low-voltage relay etc.
