CuNi6 Wire Copper Nickel Alloys NC010 120-150 HB With Good Plasticity

Product Introduction

CuNi6 wire (NC010) is a copper-nickel resistance alloy wire, mainly composed of copper and 6% nickel. It has a low resistivity of about 0.3 µΩ·m, a low temperature coefficient of resistance of about +40 ppm/°C, and can work stably at temperatures up to 220°C. The tensile strength of CuNi6 wire is usually between 400-600 MPa, the yield strength is about 250-350 MPa, and the elongation remains above 10%, showing good mechanical properties and plasticity. In addition, CuNi6 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, CuNi6 wire is widely used in the electronic and electrical fields, such as the manufacture of 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 CuNi6 wire make it an ideal choice for applications such as high-precision resistor components and sensors.

Specific Applications

1. ​Heating cables: The low resistivity of CuNi6 alloy makes it suitable for low-temperature applications, such as heating cables.
2. High temperature and high pressure environment: CuNi6 alloy performs well in high temperature and high pressure environments and is suitable for sensors and resistor elements in aerospace equipment. Its high temperature stability and fracture toughness make it an ideal material.
3. Corrosion-resistant parts: Due to its good corrosion resistance, CuNi6 alloy is widely used in marine engineering as contact materials in submarine cables, ship electrical systems, etc., ensuring stable operation in corrosive environments such as salt spray and seawater.
4. High temperature and high pressure environment: In harsh environments of high temperature and high pressure, CuNi6 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: CuNi6 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 between 400-600 MPa, the yield strength is about 250-350 MPa, and the elongation is maintained above 10%, 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 Brinell hardness value is generally between 120-150 HB, and it has strong wear resistance.
• Stable high temperature performance: The heat resistance limit of CuNi6 alloy is as high as 500℃ or more. Even at extremely high temperatures, it can maintain the stability of its resistance and is almost unaffected by temperature fluctuations.
• Good processing performance: CuNi6 alloy has good plasticity, especially when drawn into wires and tubes, it can achieve more precise dimensional control. Through proper annealing treatment, the tensile strength and ductility of the alloy will be further improved, while the resistance characteristics remain stable.
