CuNi23 NC030 High-Strength And Conductivity Alloy For Heat Exchangers In Engineering

CuNi23 NC030 High-Strength and Conductivity Alloy for Heat Exchangers in Engineering

CuNi23 is a copper-nickel alloy composed of 77% copper and 23% nickel, offering a combination of excellent corrosion resistance, mechanical strength, and thermal stability. It is particularly effective in marine environments, where it resists saltwater corrosion, making it ideal for applications in shipbuilding, offshore equipment, and seawater cooling systems.

This alloy also provides good electrical conductivity and is non-magnetic, making it suitable for use in electrical contacts, resistors, and electronic components where magnetic interference is a concern. CuNi23 maintains high tensile strength and is resistant to erosion and cavitation, making it useful for marine propulsion systems, heat exchangers, and piping systems exposed to harsh conditions.

With its ability to be easily fabricated, welded, and formed, CuNi23 is versatile for applications requiring complex shapes or high-performance components. It also performs well under high temperatures, making it suitable for use in aerospace and automotive industries.

In summary, CuNi23 combines corrosion resistance, strength, and formability, making it an ideal choice for demanding industrial, marine, and electrical applications.

Main physical properties:

Some key features of CuNi23 include:

1. Outstanding Corrosion Resistance

• CuNi23 excels in corrosive environments, particularly in saltwater and marine applications. Its ability to withstand corrosion and biofouling makes it ideal for use in seawater cooling systems, shipbuilding, and offshore structures.

2. High Strength and Durability

• This alloy offers high tensile strength and good mechanical properties, ensuring its durability under mechanical stress and in harsh operating conditions. It maintains its performance in both high-temperature and cryogenic applications.

3. Resistance to Galvanic Corrosion

• CuNi23 is highly resistant to galvanic corrosion, making it suitable for use in marine environments where different metals are in contact, preventing degradation from electrical currents.

4. Good Thermal Conductivity

• While not as conductive as pure copper, CuNi23 still offers adequate thermal conductivity, making it useful in heat exchangers, cooling systems, and thermal management applications.

5. Non-Magnetic

• CuNi23 is non-magnetic, which is beneficial for electronic devices and applications where magnetic interference needs to be avoided, such as in electrical contacts and marine instrumentation.

6. Excellent Erosion and Cavitation Resistance

• The alloy's resistance to erosion and cavitation makes it ideal for marine hardware such as propellers, pumps, and valves that are exposed to turbulent water flow.

7. Formability and Workability

• CuNi23 is ductile and malleable, meaning it can be easily fabricated, welded, and machined into a wide range of shapes and sizes, including pipes, tubes, and fittings.

8. Electrical Conductivity

• While not as conductive as pure copper, CuNi23 retains adequate electrical conductivity for use in electrical contacts, resistor components, and electronic devices where corrosion resistance is more critical than maximum conductivity.

9. Resistant to Oxidation

• The alloy exhibits good resistance to oxidation at elevated temperatures, making it suitable for use in high-temperature applications such as in power plants and industrial systems.

Applications:

• Marine Applications: Seawater cooling systems, shipbuilding, offshore structures, propellers, and marine pumps.
• Industrial: Heat exchangers, piping systems, valves, and cooling systems.
• Electrical: Electrical contacts, resistors, connector pins, and electrical components.
• Aerospace & Automotive: High-temperature components, exhaust systems, and gas turbines.
