CuNi8 NC012 CuNi Alloy Electric Heating Wire With Low Resistivity 0.49 μΩ·Cm

Product Introduction

CuNi8 wire (NC012) is a copper-nickel resistance alloy wire, mainly composed of copper and 8% nickel. It has a low resistivity of about 0.49 μΩ·cm and can work stably at temperatures up to 200°C. The tensile strength of CuNi8 wire is usually around 270 MPa, the yield strength is about 110 MPa, and the elongation remains above 25%, showing good mechanical properties and plasticity. In addition, CuNi8 wire also has good processing properties, is easy to draw into wire, and its mechanical properties can be optimized by appropriate annealing treatment. In terms of application, CuNi8 wire is widely used in the electronic and electrical fields, such as manufacturing resistors, potentiometers, resistor networks, terminals, low-resistance resistors, heating wires and resistance wires. Its excellent corrosion resistance and oxidation resistance make it also have certain applications in marine engineering and chemical industries, such as contact materials in submarine cables and ship electrical systems. These characteristics of CuNi8 wire make it an ideal choice for applications such as high-precision resistor elements and sensors.

Specific Applications

1. Resistor elements: CuNi8 alloy is widely used to manufacture high-precision resistors, potentiometers, and resistor networks. Its low resistivity and stable resistance characteristics make it perform well in these applications.
2. Low-voltage electrical appliances: It is often used in low-voltage electrical products such as low-voltage circuit breakers and thermal overload relays, and is a key material in these products.
3. Current sensors and resistance temperature detectors: Due to its low temperature coefficient and high resistance stability, CuNi8 alloy is widely used in these high-precision measurement devices.
4. Heating cables: The low resistivity of CuNi8 alloy makes it suitable for low-temperature applications, such as heating cables.
5. High temperature and high pressure environment: In the harsh environment of high temperature and high pressure, CuNi8 alloy can maintain its mechanical properties and is widely used in important components such as pipelines, containers, and sensors.

Advantages and Characteristics

• Excellent anti-oxidation and corrosion resistance: CuNi8 alloy performs well in the atmosphere, seawater, sulfur-containing gas and other environments, can effectively resist corrosion and oxidation, and extend the service life of the material.
• High tensile strength: The tensile strength is usually above 270 MPa, and the elongation is maintained above 25%, indicating that the alloy has a certain plasticity and can produce a certain deformation under stress, and is not prone to brittle fracture.
• Medium hardness: The hardness value is usually higher than that of pure copper alloy, showing good wear resistance and durability.
• Stable high temperature performance: The heat resistance limit of CuNi8 alloy is as high as 250℃ or more. Even at extremely high temperatures, it can maintain the stability of its resistance and is almost unaffected by temperature fluctuations.
