Copper Nickel 90/10 (C70600) is the industry standard for seawater piping systems. The 90% copper and 10% nickel composition, with critical iron addition (1.0–1.8%), provides a natural copper-iron oxide film that resists seawater corrosion and biofouling. Used in marine engineering for over a century — ships, offshore platforms, desalination plants, and coastal power stations.
