In industrial fabrication and structural engineering, Cu Ni Tubes provide consistent dimensional accuracy, reliable weldability, and mechanical stability. They are frequently selected for piping networks, cooling systems, and hydraulic lines that operate under moderate to high pressure. Krygen Metalloys manufactures copper nickel tubes with strict quality control to ensure dependable performance in both onshore and offshore applications.
Cu Ni Tubes are manufactured from copper nickel alloys, commonly in grades such as 90/10 and 70/30, where copper forms the base metal and nickel enhances strength and corrosion resistance. The addition of small amounts of iron and manganese improves resistance to erosion and impingement attack, particularly in flowing seawater systems. This carefully balanced composition gives the alloy excellent resistance to biofouling and stress corrosion cracking.
Metallurgically, copper nickel tubes exhibit a single phase solid solution structure that ensures uniform mechanical properties and enhanced ductility. They offer good tensile strength, moderate hardness, and excellent formability, allowing them to be cold worked, expanded, and welded with ease. Their thermal conductivity makes them ideal for heat transfer equipment, while their natural resistance to marine growth reduces maintenance in seawater applications.
Cu Ni Tubes maintain structural integrity over extended service periods. They resist pitting and crevice corrosion in chloride rich environments, making them suitable for marine piping, condenser tubing, and desalination systems. Their performance characteristics also include good fatigue resistance and reliable behavior under fluctuating temperature conditions.
