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.
