CuMn3 Manganin Copper Resistance Wire for Shunt CuMn Copper Manganese Wire
1. Description
Cupronickel, also can be called copper nickel alloy, is an alloy of copper, nickel and strengthening impurities, such as iron and manganese.
Manganin wire is an alloy made primarily of copper, manganese, and nickel. It is known for its low electrical resistance and resistance to oxidation and corrosion. Manganin wire is often used in precision electrical and electronic applications where accurate measurement of electrical current is required.
The main characteristic of manganin wire is its low temperature coefficient of resistance (TCR), which means that its electrical resistance does not change significantly with temperature variations. This property makes manganin wire suitable for applications that require stable electrical resistance over a wide temperature range.
Manganin wire is commonly used in electrical resistors, shunts, and precision wire-wound resistors. It is also used in various scientific and industrial instruments, such as strain gauges, rheostats, and potentiometers, where accurate measurement and control of electrical current or voltage is necessary. The stable resistance of manganin wire ensures precise and reliable readings in these applications.
The alloy composition of manganin wire typically consists of approximately copper, manganese, and nickel. The specific proportions can vary slightly depending on the desired electrical properties and manufacturer specifications.
Overall, manganin wire is valued for its stability, low TCR, and excellent electrical and thermal conductivity, making it a popular choice for applications that require precise electrical measurements and control.
