The Addition of Nickel to Copper Improves Strength and Corrosion Resistance But Good Ductility is Retained. Copper-nickel Alloys have Excellent Resistance to Marine Corrosion and Biofouling.
the Two Main Alloys are 90/10 and 70/30. the 70/30 is Stronger and Has Greater Resistance to Sea Water Flow; But the 90/10 Will Provide Good Service for Most Applications and Being Less Expensive Tends to Be More Widely Used.
copper-nickel Alloys are Widely Used for Marine Applications Due to Their Excellent Resistance to Seawater Corrosion, High Inherent Resistance to Biofouling and Good Fabricability
