BRASS AND COPPER BASED ALLOYS FOR BRAZE-WELDING

February 29, 2024

Francesca

Brasses are economical alloys suitable for being used in brazing and braze-welding processes.

They are widely used in different industries: HVACR, electromechanical constructions, artistic constructions etc. In particular, for manufacturing of metal constructions (such as: metal furniture, radiators, towel warmers…), heat exchangers, means of transport, lamps, chandeliers and other artistic objects.

For high-temp brazing, our offer includes particular copper alloys that contain zinc, nickel, manganese, cobalt. That is why they are called high temperature copper alloys. They are particularly suitable for special applications, such as for manufacturing of digging tools (for excavation, drilling, mining and agricultural processing).

Brasses and copper based alloys are available in a variety of make-ups: bare and coated rods in different diameters and lengths, wires in coils and spools, strips, powders, pastes, preforms from wire and strip.

Specific fluxes, in powder, paste and liquid form, are used for braze-welding. Liquid fluxes, which are spread from the torch flame, require the use of specific vaporizers. These fluxes provide a good cleaning from oxides and they are used also with copper-phosphorus alloys.

Special safety precautions must be followed during brazing operations, because these liquid fluxes are toxic and flammable.

To safeguard the health conditions of operators involved in brazing processes, STELLA has recently introduced a selection of ECO fluxes, with non-toxic formulation.

Ag15CuP BRAZING ALLOY FOR ELECTROMECHANICAL CONSTRUCTIONS

January 11, 2023

Francesca

The electrical construction industry is constantly evolving.

In the last few years, traditional mechanics has been increasingly supported, or even replaced, by electromechanics, in which mechanical systems and electricity interact with each other.

For example, automotive sector, a key industry for mechanics, is undergoing important changes, moving toward a greater use of clean energy.

Brazing process, in particular with brazing silver-based filler metals and copper-phosphorus filler metals, is often used in electromechanics and for the construction of electrical systems. Undoubtedly, the most widely used brazing alloy is Ag15CuP (ISO 17672: CuP284, EN 1044: CP102. AWS A5.8: BCuP-5).

FEATURES AND MAKE-UPS

Ag15CuP brazing alloy (percentage composition: 15% Ag, 80% Cu, 5% P) is suitable for brazing copper and copper-based alloys, also in presence of vibrations.

STELLA offers Ag15CuP alloy in all make-ups:

  • Rods with circular, square or rectangular section, and length from 1 cm to 100 cm;
  • Wires of diameter from 0,5 mm;
  • Strips with thickness from 0,1 mm to 0,5 mm and width from 1,5 mm to 100 mm;
  • Powders and pastes;
  • Preforms from wire and strip.

In electrical systems the most used make-ups are strips and rods. We suggest the most appropriate product to any customer, according to any different specific application.

APPLICATIONS

The Ag15CuP brazing alloy is used to realize different types of electrical apparatus, from industrial constructions to home electrical systems.

Some examples:

  • Power transformers;
  • Engines and generators;
  • Relay and contacts of low, medium and high voltage;
  • Home automation technologies;
  • Mechatronic systems.

THE SOLUTION FOR ANY NEED

Our supply is very wide, suitable to meet the needs of manufacturers of electromechanical constructions. In addition to the quality of our products, we also provide a high level technical assistance in choosing the right materials and processes.

Choosing STELLA as supplier of your brazing filler metals, you will find Quality, Made in Italy Excellence, Competence and Reliability.

Are you a manufacturer of electric constructions? Which are your brazing needs?

BRAZING ALLOYS FOR HVACR INDUSTRY

September 21, 2022

Francesca

Read our BROCHURE: BRAZING TECHNOLOGIES FOR HVACR INDUSTRY

HVACR (acronym of Heating Ventilation AirConditioning Refrigeration) is one of the industries that uses a lot of different kinds of brazing alloys. Production, maintenance, and installation of Refrigerating, Air Conditioning and Heating plants depend on right brazing processes of the parts.

STELLA deeply knows HVACR industry: since 1994, in facts, we have provided more than 500 HVACR manufacturers with a wide range of brazing consumables, characterized by top quality and production efficiency. Copper-phosphorus alloys, silver alloys, brass, copper and aluminum alloys, and soft-soldering alloys, available in different dimensions and make-ups, are some of the most requested products. Moreover, thanks to our long experience in the field, we are able to offer high-level technical support in choosing suitable alloys and performing brazing operations for any specific application.

SECTOR CHALLENGES

Presently, the field is facing new challenges. New targets of HVACR are:

  • high and consistent quality,
  • energy saving,
  • healthy working conditions.

The attention to healthiness and safety represent the basis on which a new model of business should be established, in order to be prepared for the immediate future.

NEW NEEDS, NEW SOLUTIONS

STELLA suggests two product lines in order to meet these emerging demands.

  • PREFORMS FROM WIRE AND STRIP

Preforms are often used in automated processes, but they are also well suited for small series. They drastically reduce scraps and rework, that means saving time and money. In fact, each preform is studied and fine-tuned for a specific application, so the brazing joint is always as defined.

  • FLUX CORED ALLOYS

Cored alloys represent an important improvement for products’ reliability and operators’ health. Thanks to this technology, the operator is not in contact with the flux that, located inside the alloy, is released when and where necessary, in just the right amount. So, the probability of flux inclusions is reduced and less fumes are released during the process of brazing. The use of flux cored alloys is still not very popular but it is destinated to spread to the most important applications, including HVACR.
