Copper-nickel (Cu-Ni) pipe fittings are becoming increasingly popular due to their high corrosion resistance, strength, and durability. Cu-Ni 70 and 30 Pipe Fittings have become a preferred choice for different industries because they provide superior performance and reliability in severe environments.

Two main types of Cu-Ni 70 Pipe Fittings are wrought and cast fitting. Wrought fittings are manufactured through hot forming copper-nickel alloy into a predetermined shape. In contrast, cast fittings are produced through a casting process where molten metal is poured into a cast to form a shape. Wrought copper-nickel fittings are suitable for high-pressure applications because of the absence of porosity and defects. Cast fittings, on the other hand, are preferred for general-purpose applications. Cu-Ni 70 pipe fittings are perfect for seawater and other saline water applications, and they are widely used in desalination plants, petrochemical companies, shipbuilding, and offshore industries.

Cu-Ni 30 pipe fittings, also known as copper-nickel 70/30 pipe fittings, are used in industries that demand higher mechanical strength and excellent corrosion resistance. Cu-Ni 30 fittings have a lower copper content than Cu-Ni 70 fittings, making them more robust and resistant to wear and tear. They are employed in marine environments as they do not rust easily, even in saltwater conditions. Cu-Ni 30 fittings are commonly used to manufacture heat exchangers, condensers, and offshore pipelines.
Cu-Ni pipe fittings offer numerous benefits, making them ideal for different applications. They have excellent resistance to biofouling, which reduces maintenance costs in marine environments. They also have excellent resistance to stress corrosion cracking, making them suitable for constructing high-pressure systems. Cu-Ni fittings have superb fabrication properties, which can be easily formed, cut, welded, and soldered, making them the preferred alternative to other materials.



Cu-Ni 70 and 30 fittings enhance different industrial applications' overall performance and sustainability. One of the major benefits of Cu-Ni fittings is that they offer excellent resistance to seawater corrosion, which can increase the lifespan of pipes and offer cost-effective solutions. They are eco-friendly and can easily be recycled.
Cu-Ni 70 and 30 pipe fittings are an excellent alternative to other materials, particularly in industries requiring high corrosion resistance and durability. Cu-Ni 70 fittings are preferred for high-pressure applications, while Cu-Ni 30 fittings are used in marine and offshore industries. The uses of Cu-Ni fittings are diverse and widespread, and they are eco-friendly, recyclable and offer long life. The benefits of Cu-Ni fittings are numerous, making them an ideal choice for various industrial applications.
