Brazing
Widest range of in-house brazing consumables categorized by alloys
Selectarc has seven decades of brazing know-how, including the development of CuP brazing alloys and innovative products such as tubular brazing wire (cored core brazing wire) in silver, aluminum and composite (aluminum alloy and flow).
70 years of excellence in the manufacture of brazing products in Europe
With state-of-the-art manufacturing facilities, Selectarc produces hard and custom solder alloys (alloys and fluxes) for industrial solutions as well as precision solder rings and preforms. Our rich experience in brazing and a technical team made up of doctors in physics and chemistry and engineers, allow us to be present in the following main sectors of activity:
- Renewable energy, solar panels
- The automobile
- Heating and ventilation
- Air conditioning, domestic and industrial refrigeration installations
- Sanitary Plumbing
- Carbide and diamond tools
- Measuring and regulating devices
- Electromechanical constructions
- Tubular constructions
Copper-Phosphorus Brazing (manual and oven)
The Phosphorus present in Copper-Phosphorus alloys makes the alloy self-stripping on red coppers. They are mainly intended for Copper-Copper and Copper-Brass assemblies with the use of a flux. Main use for fluid transport circuits made of copper. The melting points of our alloys are guaranteed at +/- 3°C.
Forms:
- Bare rods + stripping flux (paste and powder)
Copper-Phosphorus-Silver solders
The addition of silver in Copper-Phosphorus alloys lowers their liquidus temperature. This addition also makes it possible to refine the grain, improve the electrical conductivity and increase the ductility of the alloy. They are mainly intended for Copper-Copper and Copper-Brass assemblies with the use of a flux.
Forms:
- Bare rods + stripping flux (paste and powder)
- Coated chopsticks
Solders
Braze-welding alloys allow joining Steel, Copper, Cast Iron, end to end and on large tube diameters. Their high mechanical resistance, the aesthetic result, their ease of application and their very economical aspect, make them suitable for several sectors of activity.
Forms:
- Bare rods + stripping flux (paste and powder)
- Coated chopsticks
Silver Solders
These silver alloys are used to braze: Steel, Stainless Steel, Brass, Bronze, Nickel and Copper, all ferrous and non-ferrous metals (except aluminum and manganese). The presence of silver in large quantities makes it possible to produce alloys whose melting temperatures are relatively low. There are two types of silver solders: ternary solders (composed of silver, copper and zinc) and quaternary solders (composed of silver, copper, zinc and tin).
Silver solders are recommended for all soldering methods. The coated BRAZARGENT ® rods and the TBW rods make it possible to have a simplified use of the solder, without having to manage the supply of flux manually.
Forms:
- Bare rods + stripping flux (paste and powder)
- Coated chopsticks
- TBW rods (tubular solder wires)
- Preforms (rings, billets)
Aluminum brazes
Our alloys (Aluminium-Silicon and Zinc-Aluminium) cover the majority of applications for brazing aluminum parts together or with other materials. The developments made to simplify and optimize the use of this type of solder (TBW (tubular wire) and TBM (composite wire) technologies provide stability, repeatability and profitability during soldering operations.
Forms:
- Bare rods + stripping flux (paste and powder)
- Coated chopsticks
- TBW rods (tubular solder wires)
- TBM rods (composite brazing wires)
- Preforms (rings)
Fluxes strippers
The flux must dissolve the remaining oxides, its increasing fluidity guides the operator when introducing the filler metal. A good flux delays the vaporization of the elements. Once the metal is molten, part of the flux vaporizes and another part will form residue. After brazing, the parts are freed of their flux (residue) by rinsing with hot water or mechanically.
A wide choice of customization of products, coating colors and packaging to your brand can be achieved.

Forms:
- Flux in gel, paste and powder form
Cadmium ban: Regulation (EU) n° 494/2011 of 20/05/2011
From December 10, 2011, the sale and use of hard solders containing cadmium (Cd) with a concentration greater than or equal to 0.01% by weight has been prohibited.
Alternative alloys to those containing Cadmium are available in our brazing range.
Do not hesitate to contact our technicians for further information on this subject.
