CuNi2 NC005 2.0802 C70260 Copper-Nickel Alloy Wire The Ideal Choice for Moderate Electrical Properties

CuNi2 NC005 2.0802 C70260 Copper-Nickel Alloy Wire is a copper-nickel alloy that contains approximately 2% nickel and 98% copper, offering a balanced combination of corrosion resistance, electrical conductivity, and thermal conductivity. This alloy is known for its excellent performance in environments requiring moderate corrosion resistance, good mechanical properties, and high thermal and electrical conductivity. The addition of nickel improves its strength, resistance to corrosion, and overall durability, especially in marine and industrial environments. CuNi2 NC005 2.0802 C70260 Copper-Nickel Alloy Wire is a highly versatile alloy offering a balance of corrosion resistance, electrical and thermal conductivity, and mechanical strength. With 2% nickel, it is particularly resistant to seawater corrosion, making it ideal for marine and offshore applications. Its high electrical conductivity and thermal conductivity also make it suitable for heat exchangers, electrical cables, and chemical processing equipment. While its strength may not match that of high-strength alloys, it is well-suited for many standard industrial applications requiring good performance in corrosive environments and high-temperature conditions.

Some key features of CuNi2 include:

• Composition:

Copper (Cu): 98% (provides excellent thermal conductivity, electrical conductivity, and ductility).

Nickel (Ni): 2% (enhances corrosion resistance, especially in marine and high-temperature environments, and improves strength).

Iron (Fe) and Manganese (Mn): Trace elements that contribute to strength and overall performance.

• Corrosion Resistance:

Marine and Seawater Resistance: The 2% nickel content provides the alloy with excellent resistance to seawater and marine corrosion, making it a popular choice for marine applications such as shipbuilding, offshore equipment, and seawater pipes.

Good Resistance to Mild Acids and Alkaline Solutions: It also performs well in environments with mild acidic or alkaline conditions, offering durable performance in chemical processing and industrial applications.

Anti-Fouling: The alloy’s resistance to biofouling (the accumulation of marine organisms on surfaces) makes it highly suitable for heat exchangers and marine hardware exposed to water environments.

• Mechanical Properties:

Tensile Strength and Ductility: CuNi2 alloy offers a good balance of strength and ductility, allowing it to be drawn into wire, tubes, or rods while maintaining structural integrity under stress.

Fatigue Resistance: The material can withstand thermal cycling and vibration in environments subject to mechanical stress, ensuring longevity and durability in demanding applications.

Moderate Strength: While it has excellent ductility, its strength is moderate compared to high-strength alloys, but it performs well in many standard applications.

• Electrical and Thermal Conductivity:

High Electrical Conductivity: As a copper-based alloy, CuNi2 retains excellent electrical conductivity, making it well-suited for use in electrical cables, wires, and connectors that require efficient electrical transmission.

Good Thermal Conductivity: The alloy’s high thermal conductivity also makes it ideal for applications such as heat exchangers, radiators, and other systems where efficient heat transfer is essential.

• Weldability and Fabrication:

Weldability: CuNi2 alloy can be welded using conventional welding methods, such as TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas), but care must be taken to avoid overheating or oxidation during the process.

Formability: The alloy can be easily processed into wire, sheet, strip, or tube form, making it versatile for different manufacturing processes and applications.

Applications:

• Marine and Offshore Applications: CuNi2 is widely used in marine environments for pipes, tubes, heat exchangers, and seawater-cooled systems where its resistance to corrosion in saltwater is crucial.
• Electrical Components: The alloy’s high electrical conductivity makes it suitable for manufacturing wires, connectors, electrical cables, and other electrical components.
• Heat Exchangers and Condensers: Frequently used in heat exchangers, cooling systems, and condensers where high thermal conductivity is needed for efficient heat exchange in marine or industrial processes.
• Chemical Processing: Its resistance to mild acids and alkaline solutions makes it ideal for chemical processing equipment and industrial piping.

Advantages of CuNi2 NC005 2.0802 Copper-Nickel Alloy Wire:

• Excellent Corrosion Resistance: Especially in marine and seawater environments, making it ideal for offshore and seawater cooling applications.
• High Electrical and Thermal Conductivity: Offers efficient electrical and thermal conductivity, ideal for heating and cooling systems, as well as electrical wiring and components.
• Good Mechanical Properties: The alloy has a balance of strength and ductility, making it easy to process into various forms, including wire and tubing, while retaining durability.
• Resistance to Biofouling: Suitable for use in marine applications exposed to water, where biofouling is a concern.
