The standards NF and DIN are substituted for the European standard NF EN 1044 of July 1999 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 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 A ternary range Silver-Copper-Zinc, with melting ranges above 720 C, and good ductility. BRAZARGENT 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 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. 5

CUPRO-FLUX X X C FH20 Main application on carbon steel. For use with CUPROX, SUPER-CUPROX and BRAZARGENT Promotes the flow of filler metal. Extremely efficient, it permits brazing POLY-FLUX X X C FH20 even on dirty surfaces. For use with CUPROX, SUPER-CUPROX and BRAZARGENT PHOSBRAZ-FLUX X C FH20 Flux powder recommended for brazing brass connections on copper piping with our Phosbraz alloy range.

Certified by ATG (French Ministry of Industry) for combustible GEL C FH10 gas installations. To be used in combination with our BRAZARGENT 400, registration n AGFLUX X X C FH10 High quality flux. Well suited for brazing steels and copper-based alloys, as well as on piping for combustible gas installations. Certified with BRAZARGENT 400 and PAG 60, registration n 1529 and n 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. PACKAGING Units of 200 g.

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 Bare, work-hardened or annealed wires. Bare, coated rods. Flux-cored rods or wires. Rings Preforms Blasting grit Powders. 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. Cuprox and Nicrox are registered trade marks. 7
