Copper Nickel : Sea Water System Components
Cast alloys such as gun metal, nickel aluminium bronze and cast copper nickel can be suitable for the casing in copper based piping systems with alloys of resistance to higher water velocities for the impeller such as alloy 400 or nickel aluminium bronze. Appropriate attention has to be given to galvanic considerations when selecting materials.

Copper-Nickel : Ship and Boat Hulls
Copper Mariner II was the first vessel to have a hull constructed from Cu-Ni clad steel. 2mm of 90-10 Cu-Ni was roll bonded to a 6mm thickness of steel. The framing was in steel. The hull was found to be readily fabricated and welded and performance as of 1988 was reported in Copper Topics, Issue 63, to be good.

Copper Nickel : Materials Selection in Sea water systems
The use of 70-30 Cu-Ni is confined to submarines where its high strength is advantageous. Due to the low design velocity and hence large pipe sizes, copper is uneconomical except for small diameter piping for essentially domestic applications, so that the real choice is between 90-10 Cu-Ni and aluminum brass.

Iron is essential for both alloys because it provides added resistance to corrosion caused by velocity effects called impingement attack. Figure 1 shows the effect of iron content on the impingement attack on 90-10 Cu-Ni from 30-day tests obtained at 3 m/s water velocity. This is taken from the data compiled by various authors and different test facilities. A distinct minimum …
