It is the alloy content in the 90/10 Copper Nickel Pipe Fittings that assists in deriving enhanced strength and better corrosion resistance. Manufacturers present the Copper Nickel 90/10 Tee and other products as per the requirements specified by the clients. They can be customized based on shape, size, dimensions, and surface finishes, depending on the application.
The UNS C70600 Reducer helps reduce flow rates across a wide range of equipment, mainly where the media used is seawater. They are used in shipbuilding since the CuNi 90/10 End Cap exhibits good resistance to seawater environments. This includes resistance to pitting and stress corrosion cracking and high resistance to crevice corrosion. The CW352h Saddle is also famous for its properties, including high weldability and fabricability; they resist biofouling, too. Good resistance in high-temperature situations makes the CuNi 90/10 Concentric Reducers find applications in condensers and heat exchangers.
The alloy has 90% copper and 10% nickel with other chemicals. On the other hand, copper-nickel alloy offers excellent corrosion-resistant stress due to adding a small amount of manganese and iron. It is easily welded and has low ductility properties with high mechanical strength. Copper nickel alloy is used in seawater and works at high temperatures and pressures.
