Tankii Manganese Copper Alloy 6j12 6j8 6j13 Manganin Heating Wire For Resistor
Product Description
Manganin wire is a type of resistance wire made from an alloy of copper, manganese, and nickel.
It has a very low temperature coefficient of resistance, which means that its electrical resistance changes very little with changes in temperature. This makes it useful in applications where precise electrical resistance is required over a wide range of temperatures, such as in electrical measuring instruments and temperature sensors.
Manganin wire is also known for its high resistance to corrosion and its ability to withstand high temperatures.
Manganin wire has various applications due to its unique properties. Some of the common applications of Manganin wire include:
-
Precision Resistors: Manganin wire is widely used in the manufacturing of precision resistors due to its low temperature coefficient of resistance. It provides stable and accurate resistance values over a wide range of temperatures.
-
Electrical Measurement: Manganin wire is used in electrical measurement instruments, such as shunts and current sensing resistors. Its low thermal electromotive force (EMF) and high resistance make it suitable for precise current measurement.
-
Thermocouples: Manganin wire is used in the construction of thermocouples, which are temperature sensors. It is often combined with other metals, such as copper or constantan, to form a thermocouple junction that generates a voltage proportional to the temperature difference.
-
Strain Gauges: Manganin wire is used in strain gauges, which are devices that measure strain or deformation in materials. The wire is bonded to a flexible backing material and changes its resistance when subjected to mechanical stress, allowing for accurate strain measurements.
-
Electrical Heating Elements: Manganin wire is used in electrical heating elements due to its high electrical resistance and low temperature coefficient of resistance. It is commonly used in applications where precise and stable heating is required, such as in industrial furnaces and appliances.
These are just a few examples of the applications of Manganin wire. Its unique combination of properties makes it suitable for various electrical and temperature measurement applications.
