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.
