Chemical Composition (Cu-Ni 90/10)

Mechanical Properties

Key Advantages

1. Superior Corrosion Resistance
   Outstanding performance in seawater, brackish, and cooling-tower water, resisting pitting and biofouling.

2. Monometallic Construction
   Integral fins eliminate galvanic concerns—no dissimilar-metal corrosion.

3. High Thermal Conductivity
   Copper-nickel alloy provides better heat transfer than stainless steels.

4. Mechanical Durability
   Excellent toughness and fatigue resistance under thermal cycling and vibration.

5. Low Maintenance
   Natural resistance to marine growth yields longer clean-water intervals.

Typical Applications

• Marine Condensers

• Seawater-Cooled Heat Exchangers

• Desalination Plant Coolers

• Offshore Platform Cooling Systems

• Power Plant Condensers

• Chemical and Petrochemical Coolers
