• 70/30 Cupro Nickel is mainly preferred when the severity of service condition (Cooling water, steam, condensate, temperature, etc.) is such as to virtually rule out all other copper metals.
• Due to its hardness and to the type of oxide whereby its surface is self-protected, 70/30 Cupro Nickel has excellent resistance to impingement and erosion-corrosion by of suspended solids in sea water flowing at up to 3-3.5 m/s (10-11.5 ft /s).
• Like all Cupro-nickels, 70/30 Cupro Nickel is virtually immune from stress-corrosion cracking.
• It can be very sensitive to deposit attack and is therefore not recommended for stagnant or slow moving (under 1 – 1.2 m/s or 3.5-4 ft/s) water.

70/30 Cupro Nickel is very widely employed in water desalination plants, especially in the most critical areas such as the heat reject and brine heater stages, as well as in the under cooling areas of power station condensers, in the chemical, petrochemical and food processing industries and, more generally, in all applications where top corrosion resistance is required from both the shell and tube side.


Copper Nickel 70/30 Tubes / Pipes is a premium product of our production house. It has some excellent features which make it useful in various sectors. Cupro Nickel 70/30 is the most common alloy that gets used in the production of tubes. As the name suggests, it has 70:30 proportion of Cu and Ni content and a modest amount of iron (Fe) and manganese (Mn). This slightly improves its strength as compared to Cupro Nickel 90/10, making it more demanding. It offers excellent resistance to pitting and crevice corrosion as well as to stress cracking corrosion in general conditions and also in high-velocity waters having velocity up to 4.5m/s and in polluted seawater. It possesses good strength and toughness along with excellent drawability, machinability, tensile strength, and hardness. It also offers resistance to biofouling. It has a good elongation capacity of up to 27%.

  • What is the Difference Between 90/10 and 70/30 Copper-Nickel?

    The main difference between 90/10 Copper-Nickel and 70/30 Copper-Nickel lies in their composition, corrosion resistance, and strength:

  • Composition:
    • 90/10 Copper-Nickel Contains 90% copper and 10% nickel.
    • 70/30 Copper-Nickel Contains 70% copper and 30% nickel.
  • Corrosion Resistance:
    • 90/10 Copper-Nickel provides good corrosion resistance in less aggressive marine environments.
    • 70/30 Copper-Nickel offers superior corrosion resistance, making it more suitable for harsher environments like offshore platforms and desalination plants.
  • Strength:
    • 90/10 Copper-Nickel is softer and more ductile, making it easier to form.
    • 70/30 Copper-Nickel is stronger and more durable, ideal for high-stress applications.
  • Cost:
    • 90/10 Copper-Nickel is more affordable due to its lower nickel content.
    • 70/30 Copper-Nickel is more expensive due to the higher nickel content and enhanced performance.
  • In summary, 90/10 Copper-Nickel is suitable for less demanding applications, while 70/30 Copper-Nickel is ideal for more aggressive, high-performance environments.
