The Introduction of CuNi 90/10 and CuNi 70/30 Alloy :
The Attractive corrosion and biofouling -
Resistance of copper-nickel alloys in seawater
and related environments have Led to their
substantial use in marine service for many years.
The two main, wrought copper-nickel Alloys
chosen for seawater service contain 10% or 30%
Nickel, respectively. Development work began in
the 1930s in response to A requirement by the
British Navy for in improved condenser material.
Since the 1950s, the 90-10 Alloy has become
accepted for naval service. In naval vessels, the
90-10 copper-nickel is preferred for surface
ships; Whereas, the 70-30 alloy is used for
submarines because its greater strength makes it
more acceptable for the higher pressures
encountered. These alloys are also used for
power station condensers and offshore seawater
pipe work on oil/gas platforms: Large quantities
are selected for the desalination industry and
they are additionally used for cladding and
sheathing of marine structures and hulls.

GENERAL INFORMATION
THE FABRICATION TECHNIQUES FOR COPPER NICKEL ALLOY
Heating
In the presence of contaminants such as sulphur,
phosphorus, lead and other low-melting-point meals,
copper alloys may become embrittled when heated.
It is therefore important that the work piece is clean
and free from contaminants before heating. Sources
of deleterious substances are marking and
temperature-indicating paints and crayons,
lubricating grease and fluids, fuels etc. Fuels must be
low in Sulphur; e. g. natural gas and liquid petroleum
gas should contain less than 0.1% and town s gas
0.25% maximum of sulphur. Fuel oil should contain a
Maximum of 0.5% sulphur. (all percentages are by
weight.) For Cunifer 10 and Cunifer 30 the furnace
atmosphere should be neutral or very slightly
reducing. Electric heating is recommended.
Hot working
Hot working may be carried out in the following
ranges :
Cunifer 10 950 - 840 (1750 - 1550 )
Cunifer 30 1000 - 840 (1830 - 1550 )
See also the later section on got bending. The
material may be charged into the furnace at
maximum working temperature and allowed to soak
until the work piece is uniformly heated,
approximately 6 minutes 0 /100mm(4in) of section.
The material should then be withdrawn immediately
and worked within the specified range. Prolonged
soaking should not be allowed. If during working,
temperature of the metal falls below the specified
minimum it must be reheated. Air cooling is
satisfactory.
Cold Bending
Pipes are normally supplied in the annealed
condition. If possible, the tube should be bent using
bending machines when the radius of curvature is
equal to or greater than three times the diameter.
tubes up to 80mm(3in) diameter may be cold bent
with radius of curvature equal to twice the diameter.
For bend radii less than this it is advisable to use
fittings. Where cold bending is done without the use
of a tube bending machine the tube must be filled.
The most usual filler are dry silica sand free from all
carbonaceous matter and sodium thiosulfate (hypo).
The tube must be tightly packed. After bending it is
important that the filler is completely removed and
the tube thoroughly cleaned.
Annealing
Metallurgical annealing is not necessary after hot
working. For Cunifer 10 and Cunifer 30 a full anneal is
achieved by heating to 750 - 840 (1380 - 1550 ) but a
considerable degree of softening can be obtained b
heating at 600 - 650 (1100 - 1200 ) Stress relief can be
achieved by heating within the range 350 - 450 (660 -
840 ).
Pickling
After hot and/or cold bending, cleaning and stress
relieving, all traces of scale should be removed by
pickling or acid cleaning. A suitable pickling solution is
5 to 10% of sulphuric acid plus 25 -50 g/l(4 8 oz/gal.)
of sodium dichromate. After picking, the tube should
be thoroughly rinsed in hot, fresh water.
Joining
Metallurgically, Cunifer 10 and Cunifer 30 are solid-
solution alloys with no deleterious second phases and
experience no phase transformation during heating
and cooling. They are usually welded or brazed in the
annealed condition. It is also essential that the
surfaces adjacent to the joint must be clean and free
from oxide. To remove oxide and other
contaminants, an area approximately 25mm wide on
each side of the joint should be prepared by scratch-
brushing with a clean, stainless steel brush used only
for copper alloy. This is followed by degreasing with a
non-toxic non-flammable solvent. No pre-heat is
required, but the material must be free from
moisture. In cold or humid conditions, it should be
warmed to about 25ºC. Interpass temperature should
be controlled and should not exceed 10ºC. Modern
welding techniques such as TIG and MIG may be used
in addition to brazing for the joining.

GENERAL INFORMATION
Welding Consumables
It is usual practice to weld Cunifer 10 with 70/30
copper-nickel bare filler metal. Flux-coated
electrodes can be used for wall thicknesses of above
6mm. Welding consumables of almost matching
composition to Cunifer 10 are, however, available.
Under certain circumstances the use of a nominally
70/30 nickel-copper electrode or filler metal,
particularly for dissimilar metal joints, is suggested.
Cunifer 30 can be welded with 70/30 copper-nickel
filler metal.
Table 1 gives details of material specification.
Welding Consumable Specifications
Figure 1 :
Suggested joint preparations for the welding of
Cunifer 10 and Cunifer 30.
Manual metal arc welding is preferably carried out in
the down-hand position. Positional welding can be
performed successfully by skilled operators.
Positional welding is facilitated by making the root
run by the TIG process. Direction of travel is then
reversed and welding continued with a weave motion
TIG is preferred for metal thicknesses up to and
including 6mm(0.2in). TIG welding may also be used
for the root runs in thicker material, the fill-up runs
being deposited by the manual metal arc process.
For Cunifer 10 and Cunifer 30, direct current is
required. For all these materials shielding gas is
99.95% pure argon which is also used as the back
purging gas for Cunifer 10 and Cunifer 30.
Satisfactory filler wires are given in table 1 and
suggested edge preparations are shown in figure1.
Table 2 gives typical operating data for TIG welding.

Welding
Whichever process is used, tack welds should be
kept to a minimum and as short as possible. Tack
welds should be deposited in the opposite direction
to the subsequent weld run and each tack must be
thoroughly cleaned before welding commences.
Manual metal arc welding is applicable to Cunifer 10
and Cunifer 30 with thicknesses greater than 6mm.
The majority of flux-coated electrodes are
recommended for operation with direction current,
electrode positive.
