Copper Nickel Spectacle Flanges are generally made from Cu-Ni alloys like 90/10 or 70/30, which include copper, nickel, iron, manganese, and trace elements that boost corrosion resistance in seawater. These alloys are known for their excellent resistance to biofouling, erosion, and stress corrosion cracking. On the mechanical side, the flanges deliver impressive tensile and yield strength, along with superior ductility and consistent performance across a range of temperatures. Their design ensures reliable operation even in high-salinity and high-moisture conditions. The spectacle design makes it easy to switch between open and closed positions, ensuring safe operation and maintenance of the system.
