Copper Nickel tubes C70600

UNS C70600 copper nickel alloy pipes are widely used in various fields such as marine engineering, chemical engineering, energy engineering, and ocean engineering due to their excellent mechanical properties and corrosion resistance. Commonly used in the manufacturing of pipeline systems, condensers, evaporators, heat exchangers, and various high-strength corrosion-resistant parts.
Copper nickel alloy UNS C70600 is a copper based alloy with nickel as the main alloying element. The copper content is about 90%, and the nickel content is about 10%. The thermal conductivity of copper nickel alloy is close to that of carbon steel, the coefficient of thermal expansion is close to that of austenitic stainless steel, and the melting point is 1149 ℃. Copper nickel alloy UNSC70600, commonly known as white copper, has excellent seawater corrosion resistance and mechanical properties, and is widely used in seawater cooling pipeline systems on offshore platforms.

C70600 Main Applications
Mainly used for condensing tubes in thermal power generation, nuclear power, shipbuilding, seawater desalination, and marine engineering industries. In the nuclear and thermal power industries, copper nickel alloy condenser tubes have been replaced by titanium and stainless steel tubes. However, in the fields of shipbuilding, seawater desalination, and ocean engineering, copper nickel alloy condenser tubes still maintain enormous application potential and are irreplaceable. Relevant data shows that in areas with high seawater flow rates, materials with high seawater corrosion resistance include stainless steel, Monel alloy, and copper nickel alloy. Duplex stainless steel also has good corrosion resistance, but its thermal conductivity is about 38% of that of copper nickel alloy. Monel alloy is too expensive and has low practical value. Copper nickel alloy material is a commonly used material for manufacturing seawater pipeline systems, but its service life is limited and requires regular replacement.
