C70600 copper-nickel tubes, composed of 90% copper and 10% nickel, are engineered for exceptional corrosion and biofouling resistance in harsh marine and industrial environments. This alloy offers superior resistance to impingement attack, stress corrosion cracking, and seawater-induced erosion, making it a trusted choice for high-velocity cooling systems.

Thanks to their durability and anti-fouling properties, CuNi 90/10 tubes are widely used in marine condensers, heat exchangers, and desalination plants, where they outperform other copper alloys under demanding thermal and chemical conditions.

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

• 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.
