silver brazing alloys

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 fl ux 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 fi t-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-fl uxing at the brazing temperature, when used on pure copper. Phosphorus in the fi ller material reduces the copper oxide. In all other cases, the use of a fl ux is necessary.The fl ux 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 fi ller metal in the joint.

For each operation, the fl ux must be selected, according to :• joint materials,• fi ller alloy selected,• temperatures, heating mode and duration.

This means no «universal» fl ux exists, for all applications. The REB® fl ux range makes it possible to meet most problems encountered.

REMARKS

All brazing fl uxes contain aggressive products. Therefore, we suggest the following:• Work place : remove all fl ux waste to

avoid further corrosion. Our fl uxes 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 alloys

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 fl uidity and strengthens a brazed joint.

MANGANESE, TIN, IRON…Improve the characteristics of certain alloys.
