C70600 Cupro-Nickel 90/10 Manufacturer & Supplier
Ninety-ten cupro-nickel — the default seawater tube. Ten percent nickel with iron and manganese gives a self-repairing oxide film that resists seawater, and copper's inherent biofouling resistance keeps the bore clear. Velocity must stay under about 2.5 m/s or the film erodes.
