Key benefits
Outstanding resistance to seawater corrosion and biofouling: performs reliably in marine environments with minimal maintenance or cleaning.
Superior protection against impingement and erosion: withstands high-velocity flows better than aluminum brass or admiralty brass.
High resistance to stress corrosion cracking (SCC): ensures structural integrity in thermal cycling and chemically aggressive systems.
Excellent thermal conductivity: delivers efficient heat transfer in large-scale cooling and heat exchange applications.
Reliable long-term performance: reduces downtime and total cost of ownership in mission-critical systems.
Meets international standards: produced in compliance with ASTM B111 and other industry-specific specifications.




Applications
C70600 copper-nickel tubes are commonly used in:
Heat exchangers, condensers, and cooling systems in marine and offshore environments
Desalination equipment for seawater treatment and brine circulation
Chemical and industrial piping systems exposed to aggressive media
Power generation and shipboard thermal systems
Ballast water systems and ship hull coolers
Oil & gas platforms and refineries operating near coastal areas
FAQ
Q: Can c70600 withstand high flow velocities?
A: Yes, it has excellent resistance to erosion-corrosion caused by high-velocity seawater.
Q: Is c70600 resistant to biofouling?
A: Yes, its surface is less conducive to marine organism attachment compared to other materials.
Q: What are the temperature limits for c70600?
A: It can be used in temperatures up to approximately 400°C (752°F) for continuous service.
Q: How does c70600 compare to other copper-nickel alloys?
A: C70600 (90/10 CuNi) offers a good balance of cost and performance, while C71500 (70/30 CuNi) has higher strength and corrosion resistance but is more expensive.
