Product Description
Manganin Copper-Nickel Alloy Overview
Manganin is a precision electrical resistance alloy composed of copper, manganese, and nickel, offering exceptional resistivity, low temperature coefficient of resistance, and minimal thermal effect against copper. This alloy maintains excellent electrical resistance performance over extended periods, making it ideal for applications requiring precise measurements and long-term stability.
Available Alloy Types
We offer comprehensive Cu-Ni alloy grades including:
- CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi44
- NC003, NC005, NC010, NC012, NC015, NC020, NC025, NC030, NC035, NC040, NC050
Material Properties
Pure copper with nickel addition significantly enhances strength, corrosion resistance, hardness, electrical resistance, and pyroelectric properties while reducing temperature coefficient of resistivity. Cupronickel alloys offer superior mechanical and physical characteristics compared to other copper alloys.

Application Guidelines
Manganin wire is widely used in low-voltage instrumentation applications requiring high precision. For optimal performance, carefully stabilize resistors and avoid exposure to temperatures exceeding +60°C to prevent oxidation and resistance drift. This alloy serves as a cost-effective replacement for silver solder in hard metal mounting applications.
