5. What are the advantages of Copper Nickel 70/30 Sheet?
Resistant to seawater, brine, and chloride ions, outperforming stainless steel in marine environments.
Forms a protective oxide layer that prevents biofouling and erosion.
Withstands mechanical stress, vibration, and thermal cycling without cracking.
Easily fabricated into complex shapes (e.g., bends, flanges) without losing integrity.
Efficient heat transfer in heat exchangers, reducing energy consumption.
Naturally inhibits marine growth (e.g., barnacles, algae) without toxic coatings.
Lifespan of 20–30 years in seawater applications, minimizing replacement costs.
Can be welded or brazed using standard techniques, simplifying installation.
Works with other metals (e.g., steel, aluminum) when properly insulated to prevent galvanic corrosion.
100% recyclable at end-of-life, aligning with green initiatives.
