CuNi6 NC010 CuNi Alloy High-efficiency copper-based low resistance heating alloy wire for electrical heating

Copper-based low resistance heating alloy wire is a specialized type of wire crafted from a blend of metals, primarily consisting of copper as the base material. This alloy is engineered to possess specific properties ideal for applications requiring efficient electrical conduction and heat generation.

The alloy predominantly comprises copper, typically supplemented with other metals such as nickel, manganese, and sometimes chromium. These additional elements serve to enhance the wire's electrical and thermal properties while maintaining its mechanical integrity.

Main technical data.

In addition to its low electrical resistance, the alloy possesses high thermal conductivity. This means that it can effectively dissipate heat generated during operation, preventing overheating and ensuring consistent performance over extended periods.

Overall, copper-based low resistance heating alloy wire offers a combination of electrical efficiency, thermal performance, and mechanical robustness, making it an ideal choice for a variety of heating applications, including resistive heating elements, electrical appliances, industrial furnaces, and heating cables. Its versatility, coupled with its ability to deliver consistent and reliable performance, positions it as a cornerstone material in modern electrical engineering and heating technology.

Some key features of CuNi-6 include:

1. ​Corrosion Resistance: CuNi6 exhibits superior corrosion resistance, especially in marine and aquatic environments due to its ability to form a protective oxide layer.
2. High Thermal Conductivity: While not as conductive as pure copper, CuNi6 still has good thermal conductivity, which is useful in applications involving heat transfer.
3. Moderate Electrical Conductivity: The alloy has electrical conductivity that is lower than pure copper but still suitable for certain electrical applications.
4. Strength and Ductility: CuNi6 has good strength and ductility, allowing it to be formed and shaped without breaking, which is beneficial for manufacturing processes.
5. Resistance to Stress Corrosion Cracking: This alloy has a good resistance to stress corrosion cracking, which is a common failure mode in many environments.
6. Low Expansion Coefficient: CuNi6 has a low coefficient of thermal expansion, making it suitable for applications where dimensional stability over a range of temperatures is important.
7. Age-Hardening Capabilities: Although not typically aged, the alloy's strength can be improved through heat treatment processes.
8. Machinability: CuNi6 is relatively easy to machine, which is an important consideration for manufacturing parts with complex geometries.
9. Weldability: The alloy can be welded using various methods, making it suitable for applications that require assembly by joining.
10. Aesthetics: CuNi6 maintains an attractive finish and is often used for applications where appearance is important, such as in architectural and decorative elements.
11. Biofouling Resistance: In marine applications, CuNi6 resists the accumulation of organisms on its surface, reducing the need for frequent cleaning or the use of antifouling paints.
12. Recyclability: CuNi6 can be recycled, contributing to its sustainability and reducing environmental impact.

Applications:

• Electrical resistors and resistance heating wire for heating elements due to its lower resistivity compared to other copper-nickel alloys like CuNi44.
• Used in the manufacture of heating cables with low heating conductor temperature for dynamo slip rings, anodes for TV tubes, and low-resistance electrical resistors.
• Marine service for seawater systems, condensers, and piping due to its attractive corrosion and biofouling resistance.
• Coinage due to its tarnish resistance, color, and ease of processing, with the alloy CuNi25 being a common choice for this application.
