Manganin strips are a common form of the manganin alloy used in various electrical and electronic applications. Manganin strips have the following key characteristics:

1. Material Composition:

   • Manganin strips are typically composed of the standard manganin alloy, which contains around 84% copper, 12% manganese, and 4% nickel.

2. Physical Properties:

   • Manganin strips are available in a range of thicknesses, typically from 0.01 mm to 1.0 mm.
   • The width of manganin strips can vary, but common widths include 2 mm, 5 mm, 10 mm, and 20 mm.
   • Manganin strips have a flat, rectangular cross-section.

3. Electrical Properties:

   • Manganin strips exhibit an extremely low temperature coefficient of resistance, typically around 0.00002 per degree Celsius.
   • The electrical resistivity of manganin strips is around 44 microohm-cm at 20°C.
   • Manganin strips are used to fabricate highly accurate and stable resistors and other precision electrical components.

4. Applications:

   • Manganin strips are commonly used in the construction of precision resistors, burden resistors, and shunt resistors.
   • They are also used in Wheatstone bridges, voltage dividers, and other sensitive electrical measurement circuits.
   • Manganin strips can be further processed, such as by winding or etching, to create specific resistor designs.

The combination of stable electrical properties and corrosion resistance makes manganin strips a preferred choice for applications where consistent and reliable resistance values are critical, such as in scientific instrumentation, industrial controls, and metrology.
