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:
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.
