🔍 Key Concepts

• Corrosion resistance of copper alloys in seawater and cooling systems • Typical uses of red brass, manganese bronze, copper-beryllium, and cupro-nickel aboard ships • Materials commonly chosen for condenser and heat‑exchanger tubes in marine service

💭 Think About

• Which alloy family is especially known for resisting seawater corrosion and biofouling in condensers and heat exchangers? • Think about where you have seen each of these alloys used on a vessel: which ones are more for high‑strength mechanical parts versus tubing for cooling systems? • Which of these materials is specifically associated with tubes and piping carrying seawater rather than with fittings, springs, or high‑strength fasteners?

✅ Before You Answer

• Verify which option is most widely used for heat‑exchanger and condenser tubes in marine service. • Check which alloy is noted for excellent resistance to seawater corrosion rather than just good mechanical strength. • Eliminate alloys commonly used for high‑strength parts, bearings, or springs rather than for long runs of thin‑walled tubing.
