Detailed Product Description

High-Strength CuNi23 NC030 Alloy Suitable for Applications Requiring Magnetic Interference Resistance

 

CuNi23 NC030 Alloy Wire is a copper-nickel alloy consisting of approximately 23% nickel and 77% copper. This specific alloy, often referred to as CuNi23, is recognized for its excellent resistance to corrosion, especially in marine environments, chemical processing, and heat exchangers. CuNi23 is known for maintaining strength and durability in environments that would typically cause copper or other metals to degrade.

 

CuNi23 NC030 Alloy Wire is a versatile and high-performance copper-nickel alloy, primarily used in environments that require excellent corrosion resistance, especially in seawater, chemical processing, and high-temperature applications like heat exchangers. With good mechanical properties, non-magnetic characteristics, and the ability to withstand corrosive atmospheres, CuNi23 is commonly found in marine, oil and gas, and industrial applications. Although it has lower electrical and thermal conductivity compared to pure copper, its superior corrosion resistance and strength make it a valuable choice for demanding industrial environments.

Key Features of CuNi23 NC030 Alloy Wire:

  • Composition:

Copper (Cu): 77%

Nickel (Ni): 23%

The addition of nickel enhances the alloy's resistance to corrosion, particularly in seawater and acidic environments.

  • Corrosion Resistance:

CuNi23 exhibits superior corrosion resistance, especially in seawater, marine environments, and mildly acidic or neutral environments.

It is commonly used in applications where other alloys, such as pure copper, would quickly corrode, such as in marine piping systems, heat exchangers, and offshore equipment.

  • Mechanical Properties:

Strength and Toughness: The alloy offers a good balance of strength and ductility, making it suitable for various mechanical applications.

CuNi23 has a moderate tensile strength, which provides durability and resistance to mechanical stress in demanding conditions.

Formability: It is easily formed into wires, sheets, tubes, and other components.

  • Electrical Conductivity:

While CuNi23 offers lower electrical conductivity than pure copper, it still maintains satisfactory conductivity for many applications, particularly where mechanical properties or corrosion resistance are prioritized over electrical performance.

  • Thermal Conductivity:

The alloy has good thermal conductivity, though lower than that of pure copper, making it suitable for heat exchanger applications.

  • Weldability and Fabrication:

CuNi23 is easy to weld and can be used in various fabrication methods, including soldering, welding, and machining. It is widely used in industries where high-precision components are required.

  • Non-Magnetic:

CuNi23 is a non-magnetic material, making it suitable for use in applications where magnetic properties could interfere with the operation or performance of devices, such as in electrical components and sensitive measuring instruments.

 

Applications:

  • Marine Applications: Ideal for components exposed to seawater, such as marine hardware, pipes, valves, and fittings.
  • Heat Exchangers: Due to its resistance to corrosion and good thermal conductivity, it is used in heat exchangers, particularly those operating in seawater or corrosive chemical environments.
  • Chemical Processing Equipment: Common in applications like pumps, valves, and tubing in the chemical industry where resistance to aggressive substances is essential.
  • Oil and Gas: Used in offshore oil rigs, pipelines, and subsea equipment due to its excellent performance in seawater.
  • Electrical Contacts and Connectors: Though not as conductive as pure copper, CuNi23 is used in applications where mechanical properties and corrosion resistance are needed alongside electrical conductivity.

 

Resistance to Sulfur and Corrosive Atmospheres:

  • CuNi23 has better resistance to sulfur and corrosive gases than pure copper, making it ideal for use in environments with exposure to sulfur or chemical contaminants.

 

Advantages of CuNi23 NC030 Alloy Wire:

  • Corrosion Resistance: Outstanding performance in marine environments and against corrosive gases, acids, and salts.
  • Strength and Durability: Stronger than pure copper and retains good toughness, making it ideal for structural applications.
  • Non-Magnetic: Ideal for use in magnetic-sensitive environments.
  • Weldability and Fabricability: Easy to work with in a variety of manufacturing processes.
  • Versatility in Applications: Suitable for a wide range of industries, including marine, chemical processing, heat exchangers, and oil & gas.

 

Limitations of CuNi23 NC030 Alloy Wire:

  • Lower Electrical Conductivity: While suitable for many applications, its electrical conductivity is lower than pure copper, which limits its use in high-conductivity applications.
  • Cost: Copper-nickel alloys like CuNi23 tend to be more expensive than pure copper, which may be a consideration in cost-sensitive applications.
  • Thermal Conductivity: While good, its thermal conductivity is less than that of pure copper, which might limit its performance in highly demanding heat transfer applications.
