Working Mechanism

How Cupro Nickel 70/30 Coils Works

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.
