Cupro Nickel 90/10 (UNS C70600) is a widely used copper–nickel alloy composed of approximately 90% copper and 10% nickel, with small additions of iron and manganese. To begin with, this grade is well known for its excellent resistance to seawater corrosion, good thermal conductivity, and superior resistance to biofouling. Furthermore, it offers excellent formability, weldability, and ease of fabrication — making it ideal for complex piping and heat transfer applications.
Why do marine engineers and offshore designers choose Cupro Nickel 90/10 for critical seawater systems? First and foremost, its exceptional resistance to seawater corrosion and biofouling ensures long-term reliability in marine environments, reducing maintenance costs and downtime. In addition, it performs reliably across a wide temperature range, making it suitable for both ambient and elevated temperature services. Moreover, its good resistance to stress corrosion cracking ensures structural integrity under demanding operating conditions.
Consequently, Cupro Nickel 90/10 is widely used in seawater and cooling water systems, heat exchangers, and condensers. Furthermore, it is also trusted in shipbuilding, offshore structures, desalination plants, and marine engineering equipment. Equally important, its combination of corrosion resistance, thermal conductivity, and ease of fabrication makes it the preferred choice for applications where durability, efficiency, and long-term performance are critical.
