    Low Thermal Expansion CuNi Alloy CuNi34 For Stable Performance At High Temperatures

    Low thermal expansion CuNi Alloy CuNi34 for stable performance at high temperatures


    CuNi34 is a copper-nickel alloy with approximately 34% nickel, known for its excellent resistance to corrosion, particularly in seawater. This makes it ideal for use in marine environments such as shipbuilding, offshore platforms, and desalination plants. CuNi34 is highly resistant to pitting, biofouling, and stress corrosion cracking, which are common challenges in marine applications. Its durability in aggressive environments helps ensure long-lasting performance in conditions that would typically degrade other materials.


    The alloy also possesses good mechanical properties, offering strength, ductility, and toughness. While its electrical and thermal conductivity is lower than that of pure copper due to the nickel content, it still maintains adequate conductivity for certain industrial uses, such as heat exchangers and cooling systems.


    CuNi34 is commonly used in pipes, tubes, and marine components, where its combination of corrosion resistance, mechanical strength, and resistance to harsh conditions is critical. It is a reliable and cost-effective material choice for industries requiring durable, corrosion-resistant solutions, especially in seawater or chemically aggressive environments.

    • 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

    Some key features of CuNi34 include:

    • Corrosion Resistance:

    CuNi34 exhibits excellent resistance to seawater corrosion and is commonly used in marine engineering, such as shipbuilding, offshore structures, and desalination plants.

    It resists biofouling (accumulation of marine organisms) and is less prone to pitting corrosion compared to other copper alloys.

    • Mechanical Properties:

    The alloy has good strength, ductility, and toughness.

    It has moderate strength but remains highly resistant to stress corrosion cracking, especially in marine or aqueous environments.

    • Thermal and Electrical Conductivity:

    While copper is known for its high electrical conductivity, CuNi34 has lower conductivity than pure copper due to the presence of nickel.

    It retains reasonable thermal conductivity, which can be useful in heat exchange applications.

    Applications:

    • Marine Engineering: Due to its resistance to seawater corrosion, CuNi34 is used for components in ships, submarines, and offshore structures.
    • Heat Exchangers: It is also used in heat exchanger systems, particularly those that deal with seawater or aggressive environments.
    • Pipes and Tubes: CuNi34 is used for tubing and piping in industries like desalination and offshore oil extraction.
