Copper Steel Products Applications

Copper-nickel alloys are essential in environments where saltwater contact is constant. Key applications include:

Marine Systems: Onboard seawater desalination plants, bilge and ballast water systems, and sanitary systems.
Heat Transfer: Condensers, coolers, and other high-efficiency heat exchangers.
Safety Systems: Fire mains, sprinklers, and hydraulic lines.
Offshore Platforms: Brine systems and fuel oil/lube oil lines.
Industrial: Compressed air systems and warm water heating

Frequently Asked Questions About Copper Nickel Products

What is the main advantage of Cupro Nickel in marine environments?

Copper Nickel alloys have a natural resistance to biofouling (the buildup of algae and barnacles) and exceptional resistance to stress corrosion cracking in seawater.

What is the difference between 90/10 and 70/30 Copper Nickel?

90/10 is the most common grade for general seawater applications. 70/30 contains more nickel, making it stronger and more resistant to higher flow velocities and extreme corrosion.

Can Copper Nickel be welded?

Yes, Cupro Nickel alloys have excellent weldability using standard methods like TIG and MIG, provided the correct filler metals are used to maintain corrosion resistance.
