C70600 Cupronickel (90% Cu, 10% Ni, 1.4% Fe) ist der standard material für seawater cooling systems in naval vessels, offshore platforms, desalination plants, und power station condensers. Es combines excellent corrosion widerstand in flowing seawater mit inherent biofouling widerstand — marine organisms tun nicht readily attach zu sein surface.

Frequently Asked Questions
Warum ist iron added zu 90/10 cupronickel?
Der 1.4% iron addition dramatically improves widerstand zu impingement attack in hoch-velocity seawater (>2.5 m/s flow). Ohne der iron addition, der protective oxide film breaks ab und localized erosion-corrosion occurs. Dies war ein major innovation in der 1950s das enabled cupronickel's widespread adoption in naval systems.
