Copper Nickel Wire CuNi Alloy CuNi8/NC012/C71500 Senphus Flexibile Industrial Heating Solutionsfor Precise Temperature Control in Diverse Heating Applications

CuNi8 is a copper-nickel alloy containing approximately 92% copper and 8% nickel, with small amounts of iron and manganese to enhance its strength and corrosion resistance. This alloy is known for its exceptional performance in marine and industrial environments due to its resistance to seawater corrosion, biofouling, and erosion. CuNi8 also offers good mechanical strength and ductility, making it suitable for applications requiring durability and ease of fabrication.

CuNi8’s balance of strength, corrosion resistance, and thermal properties makes it ideal for demanding environments such as marine, industrial, and electrical applications.

Main physical properties:

Max continuous operating temperature ℃

 250
Resistance temperature coefficient x 10-5/℃(20℃-600℃) <57
Thermovoltage to copper at 20℃ in μV/K -22
Thermal expansion coefficient ×10-6/K(20℃-400℃) 17.5
Thermal conductance at 20℃ W/mK 75
Specific heat capacity at 20℃ J/gK 0.38

Some key features of CuNi-8 include:

  1. Corrosion Resistance:

    • Outstanding resistance to seawater corrosion, making it ideal for marine applications.
    • Resists biofouling, erosion, and stress corrosion cracking in harsh environments.

  2. Thermal Conductivity:

    • Good heat transfer properties, suitable for use in heat exchangers and condensers.

  3. Moderate Electrical Conductivity:

    • Useful in electrical applications such as connectors and resistance wires.

  4. Mechanical Strength and Ductility:

    • Provides a balance of good strength and excellent ductility, making it suitable for forming and fabrication.

  5. Durability:

    • Reliable and long-lasting performance in aggressive environments, reducing maintenance costs.

  6. Ease of Fabrication:

    • Excellent weldability and formability, allowing for the production of complex shapes and components.

  7. Resistance to Biofouling:

    • Naturally resists the accumulation of marine organisms, reducing maintenance in seawater systems.

  8. Versatility:

    • Suitable for both high-stress and high-temperature applications without significant degradation.

These features make CuNi8 an excellent choice for marine, industrial, and electrical applications where corrosion resistance and durability are critical.

Applications:

1. Marine Applications

Seawater Piping: Used for pipes, valves, and fittings in seawater systems, such as cooling and desalination plants.

Shipbuilding: Components exposed to seawater, including hulls, propellers, and marine hardware, due to its resistance to corrosion and biofouling.

Heat Exchangers: Tubing for heat exchangers in ship engines, desalination plants, and offshore oil rigs.

2. Power Generation

Cooling Systems: Tubes and components in heat exchangers and condensers in power plants, particularly those utilizing seawater for cooling.

Desalination: Used in desalination plants for heat exchangers that handle salty and aggressive environments.

3. Chemical and Petrochemical Industries

Chemical Process Equipment: Components in reactors, heat exchangers, and tanks exposed to corrosive chemicals.

Tanks and Vessels: Used in environments where resistance to aggressive fluids and high temperatures is needed.

4. Electrical and Electronics

Electrical Connectors: Due to its moderate electrical conductivity and corrosion resistance, CuNi8 is used for connectors, switches, and terminals.

Resistance Wires: Used in specific electrical applications requiring stable resistance properties.

5. Coinage

Coins: CuNi8 is used in minting durable coins because of its corrosion resistance, wear properties, and aesthetic appeal.

6. Architecture

Cladding and Roofing: Suitable for use in coastal areas or regions with high humidity where corrosion resistance is critical for building materials.

CuNi8’s versatility and combination of mechanical, thermal, and corrosion-resistant properties make it highly valuable in applications exposed to marine, industrial, and chemical environments.
