Common Questions and Answers
1. Why is C70600 preferred for marine applications?
Answer: C70600 Copper Nickel 90/10 is preferred for marine applications due to its
excellent resistance to seawater corrosion, biofouling, and erosion. It is used in seawater piping systems,
heat exchangers, and condensers where durability in harsh marine environments is required.
2. Is C70600 suitable for use in contact with potable water?
Answer: Yes, C70600 is suitable for use in contact with potable water due to its corrosion
resistance and compliance with drinking water standards. It is commonly used in desalination plants, water
distribution systems, and plumbing fittings.
3. How does C70600 compare to C71500 (Copper Nickel 70/30)?
Answer: C70600 (90/10) has a higher nickel content compared to C71500 (70/30), which gives
it better resistance to corrosion in marine environments. C71500, on the other hand, offers higher strength
and is typically used in applications requiring higher mechanical properties.
