Copper-Manganese-Tin Alloy Strip CuMn7Sn Resistivity 0.29 Resistance shunt Strip with Good

Manganin is an electrical resistance alloy that consists primarily of copper, manganese, and nickel. It is commonly used for making precision resistors and other electrical measurement devices due to its very low temperature coefficient of resistance and excellent stability over time.

Some key properties of manganin include:

• Composition: copper, manganese, and nickel.
• Electrical Resistivity: Approximately 29 - 90 microohm-cm at 20°C.
• Temperature Coefficient of Resistance: Extremely low, around 0.00002 per degree Celsius.
• Thermal EMF: Very low, making it suitable for precision measurement applications.
• Corrosion Resistance: Good corrosion resistance, especially in dry environments.

Manganin is valued for its ability to maintain a stable electrical resistance despite changes in temperature, making it ideal for use in resistance standards, resistor networks, and other sensitive electrical instruments. It is commonly used in the construction of high-precision resistors, burden resistors, and as the resistive material in Wheatstone bridges and other measurement circuits.

The combination of its low temperature coefficient, good stability, and corrosion resistance make manganin a popular choice for a wide range of electrical and electronic applications that require consistent and reliable resistance values.

1. 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.
