Low Resistance Heating Copper Nickel Alloy Wire CuNi1 NC003 With Resistivity 0.03, Used In Heating Cables and Resistors

CuNi1 NC003 Copper-Nickel Alloy Wire is an economical copper-nickel alloy with approximately 1% nickel, offering a balance between moderate corrosion resistance, mechanical strength, and electrical/thermal conductivity. It is suitable for marine, electrical, and industrial applications where the environment is less aggressive but still requires the corrosion resistance of nickel. While CuNi1 does not provide the same level of corrosion resistance or strength as alloys with higher nickel content (like CuNi6 or CuNi8), it remains a cost-effective solution for applications in seawater, cooling systems, and electrical components.

Main physical properties:
Max continuous operating temperature ℃ 200
Resistance temperature coefficient x 10-5/℃(20℃-600℃) <100
Thermovoltage to copper at 20℃ in μV/K -8
Thermal expansion coefficient ×10-6/K(20℃-400℃) 17.5
Thermal conductance at 20℃ W/mK 145
Specific heat capacity at 20℃ J/gK 0.38

Key Features of CuNi1 NC003 Copper-Nickel Alloy Wire:

  • Composition:
    • Copper (Cu): Approximately 99%, providing excellent electrical conductivity, thermal conductivity, and ductility.
    • Nickel (Ni): Approximately 1%, improving the alloy's corrosion resistance in marine and chemical environments, though it provides lower resistance compared to alloys with higher nickel content.
    • Other Trace Elements: Minor elements like iron (Fe) and manganese (Mn) may also be present, which contribute to the alloy's overall strength and corrosion resistance.
  • Corrosion Resistance:
    • Marine and Seawater Resistance: The 1% nickel content offers moderate resistance to seawater corrosion, making CuNi1 suitable for marine environments but less durable than higher nickel alloys (e.g., CuNi6 or CuNi8).
    • General Corrosion Resistance: CuNi1 performs well in mild acidic and alkaline environments, as well as in industrial processing applications, though its performance will be less effective in highly aggressive environments.
    • Biofouling Resistance: While it offers some resistance to biofouling, CuNi1 is less effective than higher nickel-content alloys in environments where biofouling is a concern.
  • Mechanical Properties:
    • Moderate Strength: CuNi1 provides better strength than pure copper, thanks to the small nickel addition, making it suitable for applications requiring moderate mechanical strength.
    • Workability: CuNi1 is relatively easy to form into wires, tubes, rods, or sheets, and it can be processed via cold-working and hot-working methods. It retains good ductility, making it suitable for fabrication.
    • Fatigue Resistance: CuNi1 has good resistance to thermal cycling and moderate fatigue resistance.
  • Electrical and Thermal Conductivity:
    • Good Electrical Conductivity: CuNi1 retains high electrical conductivity, making it suitable for electrical wiring, connectors, and other electrical components, though its conductivity is slightly lower than that of pure copper.
    • Good Thermal Conductivity: The alloy maintains high thermal conductivity, making it effective for use in heat exchangers, cooling systems, and thermal management applications.
  • Weldability and Fabrication:
    • Weldability: CuNi1 can be welded using standard techniques like TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding. However, care should be taken to manage heat during welding to prevent oxidation or material degradation.
    • Formability: CuNi1 is easy to process and form into various shapes such as wires, sheets, and tubes. It has good ductility, making it ideal for applications that require shaping without compromising material strength.

Applications:

  • Marine and Offshore Applications: CuNi1 is used for seawater piping, marine hardware, and heat exchangers in less aggressive marine environments where the corrosion resistance of pure copper is insufficient, but the cost of higher nickel alloys is prohibitive.
  • Electrical and Electronic Components: The alloy is suitable for wires, connectors, and other electrical components where moderate electrical conductivity and corrosion resistance are required.
  • Heat Exchangers and Cooling Systems: CuNi1 is commonly used in cooling systems, heat exchangers, and industrial equipment requiring moderate resistance to corrosion and good thermal conductivity.

Advantages of CuNi1 NC003 Copper-Nickel Alloy Wire:

  • Cost-Effective: The low nickel content of CuNi1 makes it more economical than alloys with higher nickel content, while still providing some corrosion resistance for marine and industrial applications.
  • Good Electrical and Thermal Conductivity: The alloy maintains good electrical and thermal conductivity, making it useful for applications in electronics and heat exchangers.
  • Moderate Corrosion Resistance: CuNi1 offers adequate corrosion resistance for mild marine and industrial environments, although it is not as effective as alloys with higher nickel content.
  • Formability and Workability: CuNi1 is highly formable and can be easily processed into various shapes for a wide range of industrial applications.
