The copper nickel 90/10 circle offers many advantages including particular resistance to seawater corrosion, making it ideal for the marine environment It exhibits excellent resistance to biofouling, and ensures long service under extreme conditions. The alloy also offers strong mechanical properties such as high tensile strength, durability and resistance to stress corrosion cracking. It also has excellent thermal electrical conductivity along with excellent weldability and formability. These features make the Copper Nickel 90/10 Circle desirable for applications such as heat exchangers, desalination plants, and chemical plants.
Copper-nickel 90/10 (CuNi 90/10) is an alloy composed of 90% copper and 10% nickel. It is widely used for applications requiring excellent corrosion resistance, especially in marine environments. Common uses include seawater piping systems, heat exchangers, and condenser tubes in ships, offshore platforms, and desalination plants. It is also utilized in coinage, electrical components, and automotive systems. The alloy’s ability to resist biofouling and corrosion from saltwater makes it ideal for industrial and marine applications.
