Cupro Nickel 70/30 Coils are copper-nickel alloy coils composed of 70% copper and 30% nickel, known for their excellent resistance to seawater corrosion and biofouling. These coils are widely used in marine, desalination, and heat exchanger applications. They offer superior strength, thermal stability, and resistance to stress corrosion cracking, making them ideal for harsh marine and industrial environments.
Cupro Nickel 70/30 Coils work through a protective surface layer formed by copper and nickel interaction, which prevents corrosion in seawater and saline environments. Nickel enhances mechanical strength, while copper ensures excellent thermal conductivity and resistance to marine growth.
Additionally, the alloy resists biofouling due to its natural anti-fouling properties, reducing maintenance requirements. This makes it highly effective for long-term use in marine and offshore applications where reliability is critical.
