90/10 Cupronickel (CuNi10Fe1Mn) — outstanding seawater corrosion and biofouling resistance. For seawater piping, condenser tubes, heat exchangers and ship hulls in marine service.
CuNi10Fe1Mn (EN CW352H / UNS C70600) per EN 12163. 10% Ni + Fe+Mn microstructure gives outstanding resistance to seawater corrosion, impingement attack and biofouling (anti-fouling inherent). Superior to carbon steel and most copper alloys in seawater. Standard for naval ship seawater piping systems, condenser tubes, offshore platform firewater lines and desalination plant tubes.
