Cupronickel Uses

Cupronickel for Offshore & marine- Salt water pipes and fittings, hot water tanks, salt water baffles, propeller sleeves, valve and pump components, flanges, boat hulls, marine fittings and marine hardware

Copper nickel uses in Chemical processing- Heat exchanger and cooling plant, evaporator tubes, pump and valve trim

Other uses of Cupro nickel - Power steering tube, brake lines, condenser plates, pressure vessels and distiller tubes

Copper Nickel seawater corrosion

Crevices can normally be tolerated in designs using these materials. They may foul but rarely pit.


Hastelloy C

Inconel 625

Titanium will pit at temperatures above 120°C.

Inconel 625 after 2-3 years shows signs of incipient pitting in some tests in quiet seawater

90/10 copper-nickel(1.5 Fe)Admiralty Brass Shallow to no pitting90/10 copper-nickel is standard seawater piping alloy.
70/30 copper-nickelCopperTin and aluminium bronzesAustenitic nickel cast iron Good resistance to pittingUseful in piping applications
Crevices cannot be tolerated in designs (But usable in above the waterline marine applications)
Nickel Many deep pits develop.Cathodic protection from less noble alloys required
Grade 304 Stainless Steel Many deep pits develop.Cathodic protection from steel may not be fully effective
Precipitation Hardening Grades of Stainless Steel Many deep pits develop.Cathodic protection with zinc or aluminium may induce cracking from hydrogen
Severe crevice corrosion limits usefulness
Grade 303 Stainless Steel Severe pitting.Cathodic protection may not be effective.
Series 400 (ferritic or martensitic) Stainless Steel Severe pitting.Cathodic protection with zinc or aluminium may induce cracking from hydrogen.
Useful although cathodic protection required on critical surfaces
Monel 400 (nickel-copper alloy) Pits tend to be self-limiting in depth at about 1-6 mm.No protection required for heavy sections.Cathodic protection from steel or copper base alloys will prevent pitting on O Ring, valve seats, and similar critical surfaces.
CN7M (Alloy 20)Incoloy 825 Occasional deep pits will develop.Protection not normally required for all alloy 20 pumps.Cathodic protection from less noble alloys may be necessary for O Ring and similar critical surfaces.
Grade 316 Stainless Steel Cathodic protection from zinc, aluminium, or steel is required except when part is frequently removed from seawater and thoroughly cleaned
