Corrosion and seawater resistance

At sea, a circuit has to resist corrosion for decades. We supply copper-nickel alloys for seawater systems, with full traceability.

How it is measured

Unit
Assessed per service environment
Depends on
Alloy and service environment

What we recommend, by service condition

Seawater, firefighting and ballast circuits
Copper-nickel: Navinic 10 (CuNi10Fe1Mn, C70600) or Navinic 30 (CuNi30Mn1Fe, C71500).
Marine and offshore topsides
Copper-nickel components, for their resistance in aggressive environments.
