Working Mechanism
How Cupro Nickel 70/30 Plate Works
Cupro Nickel 70/30 Plates work by forming a protective oxide layer on the surface when exposed to marine environments. This layer acts as a barrier, preventing further corrosion and enhancing the material's durability. The presence of nickel significantly improves resistance to seawater corrosion, making it ideal for marine and offshore structures.
