Detailed Product Description

Constantan Ribbon/Flat Wire 0.26mm*3mm For Electric Relay

 

Normal Manganin 47(Precision Resistance Alloy)
(Common Name:Normal Manganin,Normal Manganin 47,CuMn12Ni2 )

Normal Manganina 47 is a copper-manganese-nickel alloy (CuMnNi alloy) for use at room temperature. The alloy is characterized by very low thermal electromotive force (emf) compared to copper.

Normal Manganina 47 is typically used for the manufacturing of resistance standards, precision wire wound resistors, potentiometers, shunts and other electrical and electronic components.

 


Normal Manganin 47 widely used for precision resistors with the highest requirements, the resistors should be carefully stabilised and the application temperature should not exceed +60 °C. Exceeding the maximum working temperature in air may result in a resistance drift generated by oxidizing. Thus, the long-term stability can be affected negatively. As a result, the resistivity as well as the temperature coefficient of the electric resistance may slightly change.
 

It is also used as low cost replacement material for silver solder for hard metal mounting.The alloy's low emf vs. copper makes it ideal for use in electrical circuits, especially D.C., where a spurious thermal emf could cause malfunctioning of electronic equipment. Due to the low operating temperature, the temperature coefficient of resistance is controlled to be low over a range of 15 to 35°C .
