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.
