REBOUD-ROCHE is continuously developing its silver solder range designated BRAZARGENT.
These alloys are used for brazing steel, brass, bronze, nickel alloys and copper. Brazing Alloys from this range
are used to join most Ferrous and Non-Ferrous metals with the exception of Aluminium and Magnesium.
These Alloys have good Brazing properties and can be pre-positioned prior to heating, or manually applied
during heating. Suitable for all heating methods. Lap joints are recommended, however, butt joints can be
used where conditions are less demanding.
Clearances between 0.05-0.13 mm are recommended, depending on the Fluidity of the alloy used, in order
to achieve capillarity. A flux is necessary when brazing in open atmospheric conditions.
High silver contents in brazing alloys allow to work at relatively low temperatures.
3 MAIN FAMILIES:
BRAZARGENT 15... A ternary range Silver-Copper-Zinc, with melting ranges above 720°C, and good
ductility.
BRAZARGENT 20... A quaternary family containing the previously mentioned metal and Cadmium.
They are suitable for low temperature and good fit-up applications due to their excellent penetration.
These alloys have a high mechanical strength and they are recommended when a low melting point is
required : low tenor in zinc and cadmium.
BRAZARGENT 50... Cadmium-free A specially developed range created to replace the BRAZARGENT 20..
when the use of Cadmium is not permitted (food and sanitary industry, Middle East and Northern European
countries).
PRESENTATION Bare or Flux Coated rods, wire in coils or on spools. Under special request: Tubular Brazing
Wires (TBW*) in wire, rods, rings and pre-forms.

WHY TO USE A FLUX?
Nearly all metals exposed to the atmosphere get easily oxidized. The higher the temperature, the higher
the oxidation !
Certain brazing welding alloys, such as PHOSBRAZ® are self-fluxing at the brazing temperature, when
used on pure copper. Phosphorus in the filler material reduces the copper oxide. In all other cases, the use
of a flux is necessary.
The flux is used to permit proper formation of the joint due to three main actions: protection of joint
surfaces against oxidizing during heating, dissolution of metallic oxides and removal of residues generated
during the process, wetting of the surfaces to be assembled to permit adequate migration of the filler
metal in the joint.
For each operation, the flux must be selected, according to :
• joint materials,
• filler alloy selected,
• temperatures, heating mode and duration.
This means no «universal» flux exists, for all applications. The REB® flux range makes it possible to meet
most problems encountered.
REMARKS
All brazing fluxes contain aggressive
products. Therefore, we suggest the
following:
• Work place : remove all flux waste to
avoid further corrosion. Our fluxes
are soluble in hot water or slightly
alkaline solutions.
• Personnel: avoid fume breathing, use
safety glasses and glove protection,
use enough ventilation.
Flux dosing depends on the property
and the oxidation of pieces.

Brass welding alloys are generally used on steel, notably for the assembly of
steel tubes (bicycles, metal furniture), nickel silver, coach-building, lock-smithing,
maintenance.
Suitable for hand, furnace or carousel use.
The main element of this range is Copper, to which other metals are added.
ZINC…
Lowers the melting point and produces a corrosion-resistant and ductile brass, up
to a 40 % Zinc content.
NICKEL…
Used in conjunction with the previous two metals to form nickel silvers; high
strength alloys with good corrosion resistance.
SILVER…
Combines nearly all the qualities, except price. A small silver content in an alloy
considerably improves its fluidity and strengthens a brazed joint.
MANGANESE, TIN, IRON…
Improve the characteristics of certain alloys.
FORMS

remark
In the absence of an inert atmosphere,
the use of a flux is necessary, except when
using coated or flux-cored products.
Flux dosing depends on the properties and
degree of oxidation of the components.

marks.
