  • Tolerance of ohm/m: ±5%
  • Round wire: range from 0.04mm (0.0016″) to 12mm (0.4724″)
  • Ribbon: range from 0.05mm (0.002″) to 6mm (0.2362″), Max ratio width : thickness = 10:1

Key Features of CuNi1:

  • Composition:
  1. Copper (Cu): Predominantly 99% copper, offering excellent thermal and electrical conductivity.
  2. Nickel (Ni): 1% nickel, enhancing the alloy's corrosion resistance and strength, especially in marine and high-temperature environments.
  3. Other Elements: Small amounts of other elements (such as manganese, silicon, and iron) may be present, which contribute to the alloy's overall strength, workability, and resistance to oxidation.
  • Corrosion Resistance:
  1. Marine and Freshwater Resistance: CuNi1 has excellent resistance to seawater corrosion, making it highly suitable for marine applications, such as boat parts, shipbuilding, and offshore installations.
  2. Resistant to Fouling and Erosion: The alloy also resists biofouling, oxidation, and scaling in high-temperature aqueous environments, which is important for heat exchangers and other industrial applications exposed to water.
  3. High Resistance to Corrosion in Chemical Environments: The presence of nickel enhances the corrosion resistance of the alloy in a variety of chemical environments, especially in mild acidic or alkaline conditions.
  • Mechanical Properties:
  1. Strength and Ductility: CuNi1 alloy offers a good combination of strength and ductility, making it suitable for manufacturing wires, tubes, and rods that need to retain strength under stress while maintaining formability.
  2. Workability: It has good cold-working and hot-working properties, allowing it to be easily drawn, extruded, or formed into different shapes for various industrial applications.
  3. Fatigue Resistance: CuNi1 provides good resistance to fatigue and mechanical stress, making it suitable for use in environments where vibration or thermal cycling may occur.
  • Electrical and Thermal Conductivity:
  1. High Electrical Conductivity: Being primarily copper, CuNi1 alloy offers high electrical conductivity, making it ideal for applications like electrical cables, connectors, and wires in electrical systems.
  2. Good Thermal Conductivity: The alloy also offers good thermal conductivity, which is essential in applications where heat transfer is critical, such as in heat exchangers and cooling systems.
  • Weldability and Fabrication:
  1. Weldability: CuNi1 is generally easy to weld using conventional welding methods like TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding, although careful heat control is necessary to avoid issues with grain growth or other defects during the welding process.
  2. Fabrication: The alloy can be easily processed into various forms, including wire, strip, sheet, and tube, making it versatile for a wide range of industrial uses.

 

Applications of CuNi1:

  • Marine Applications: Due to its resistance to seawater corrosion, it is widely used in marine hardware, shipbuilding, heat exchangers, valves, and pipes exposed to seawater or brine.
  • Electrical Components: Wires and cables for electrical transmission and connectors in both marine and industrial applications where high conductivity and corrosion resistance are required.
  • Heat Exchangers and Cooling Systems: Used in heat exchangers, condensers, and cooling systems due to its good thermal conductivity and corrosion resistance in water environments.
  • Industrial Equipment: Commonly used in chemical processing, food processing equipment, and other industries requiring components with both strength and corrosion resistance.
  • Plumbing Systems: Can be found in plumbing systems where its combination of strength and resistance to corrosion is advantageous.

 

Advantages of CuNi1 NC003 Copper-Nickel Alloy Wire:

  • Excellent Corrosion Resistance: Especially in marine and freshwater environments, providing longevity and reliability for parts exposed to corrosive conditions.
  • Good Strength and Ductility: Provides a balance of mechanical strength and ductility, making it easy to form into various shapes and designs while maintaining its structural integrity.
  • High Thermal and Electrical Conductivity: Ideal for heat exchangers and electrical systems that require efficient heat transfer and low resistance.
  • Versatility: Can be used in a wide range of industries, including marine, electrical, chemical, and industrial equipment manufacturing.
  • Fabrication-Friendly: Easy to process, form, and weld into various shapes, making it a versatile material for manufacturing applications.
