Key Features of CuNi10 NC015 2.0811 C70700 Copper-Nickel Alloy Wire:

Composition:

Copper (Cu): Approximately 90%, providing excellent thermal conductivity, electrical conductivity, and ductility.

Nickel (Ni): Approximately 10%, improving the alloy’s strength and corrosion resistance, especially in marine and seawater environments.

Iron (Fe), Manganese (Mn), and Other Elements: Trace elements that contribute to the alloy's strength, resistance to corrosion, and overall durability.

Corrosion Resistance:

Marine and Seawater Resistance: CuNi10 provides superior resistance to seawater corrosion, making it ideal for applications exposed to saltwater, such as marine hardware, heat exchangers, seawater piping, and offshore equipment.

Good Resistance to Chemical Corrosion: The alloy also resists mild acidic and alkaline solutions, which makes it well-suited for use in chemical processing and industrial environments.

Biofouling Resistance: CuNi10 is resistant to biofouling, the buildup of marine organisms on surfaces, ensuring its performance in systems exposed to seawater, such as cooling systems and heat exchangers.

Mechanical Properties:

Moderate Strength: The 10% nickel content enhances the strength of CuNi10 compared to pure copper, making it suitable for applications that require moderate mechanical strength but where ductility remains important.

Fatigue and Wear Resistance: CuNi10 exhibits good fatigue resistance and can withstand thermal cycling and vibration in environments that experience fluctuating temperatures or mechanical stress.

Ductility and Workability: The alloy is highly formable, making it easy to draw into wire, tubes, rods, and sheets, and it can be processed using both cold working and hot working methods.

Electrical and Thermal Conductivity:

Electrical Conductivity: While not as high as pure copper, CuNi10 maintains good electrical conductivity, making it suitable for use in electrical components such as wires and connectors.

Thermal Conductivity: The alloy retains excellent thermal conductivity, making it ideal for use in heat exchangers, cooling systems, and other applications where efficient heat transfer is necessary.

Weldability and Fabrication:

Weldability: CuNi10 can be welded using standard methods like TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas), though it requires care to avoid oxidation or overheating during the process.

Formability: The alloy is easy to form into various shapes (such as wire, tubes, sheets) and can be cold-worked or hot-worked into various configurations for different industrial applications.

Applications:

Marine and Offshore Applications: Due to its excellent seawater resistance, CuNi10 is widely used in marine environments for seawater piping, heat exchangers, cooling systems, valves, and offshore equipment exposed to saltwater and harsh conditions.
Electrical Components: CuNi10’s good electrical conductivity makes it suitable for wires, connectors, electrical cables, and other electrical components.
Heat Exchangers and Cooling Systems: The alloy’s high thermal conductivity and corrosion resistance make it ideal for use in heat exchangers, cooling systems, radiators, and other thermal management systems in industrial and chemical processing applications.
Chemical Processing Equipment: CuNi10 is also used in chemical processing plants, industrial piping, and other systems that require resistance to mild acids and alkaline solutions.

Advantages of CuNi10 NC015 2.0811 C70700 Copper-Nickel Alloy Wire:

Superior Seawater Resistance: CuNi10 offers outstanding resistance to seawater corrosion, making it ideal for marine and offshore applications such as piping, heat exchangers, and cooling systems exposed to saltwater.
Good Mechanical Properties: With moderate strength and ductility, CuNi10 is well-suited for applications where both strength and formability are required.
High Thermal Conductivity: The alloy offers excellent thermal conductivity, making it highly suitable for heat exchangers and cooling systems that require efficient heat transfer.
