Copper-nickel alloys have earned a solid reputation in the shipbuilding and marine engineering sectors. These materials are favored not only for their exceptional corrosion resistance but also for their mechanical stability, resistance to biofouling, and ability to withstand long-term immersion in seawater. They are widely used in components such as seawater piping systems, heat exchanger tubing, valve bodies, and various structural ship fittings.
Even though copper-nickel offers natural advantages over many other marine metals, neglecting proper maintenance can still shorten its service life or reduce system efficiency. This guide provides practical, experience-based maintenance methods that help ship operators, marine engineers, and maintenance teams keep copper-nickel alloy fittings in optimal condition.
How to Maintain Copper-Nickel Alloy Ship Fittings Maintenance
1. Perform Regular Cleaning to Minimize Biofouling
Although copper-nickel alloys inherently resist corrosion and microbial attachment better than stainless steel or carbon steel, they are not completely immune to marine growth. Over time, algae, barnacles, and shell organisms can accumulate on exposed surfaces, affecting water flow, heat transfer efficiency, and overall system performance.
