INSTRUCTIONS FOR USE TECHNICAL INFORMATION Brazing is a process by which two metal parts are stably joined by the use of a filler material which is brought to fusion through the application of heat, this filler material penetrates in a capillary way between the joints to be united, connecting them definitively. Brazing, unlike welding, does not unite the two metal parts by melting them, but instead unites them by melting the filler material, which by capillarity penetrates the two metal parts to join them in a stable and permanent way. The filler material must always have a lower melting...

HOW TO CHOOSE THE ALLOY FOR BRAZING The alloy for the brazing (the so-called “brazing alloy”) has to be chosen considering various aspects, including the characteristics of the materials to be joined and their melting point. In fact, the alloy must melt at a lower temperature than the base metals, to avoid deterioration of the other materials involved in the operation. The field of application of the finished product is also important, in fact, there are alloys that have a higher resistance to environments particularly subject to corrosion, or alloys that are more suitable for jewellery...

CADMIUM-FREE SILVER BASED ALLOYS They are low temperature brazing alloys, for general use and suitable for joining base materials such as iron, carbon steel, stainless steel, copper, nickel and the alloys of these metals. Given the fluidity and excellent capillary penetration capacity, they ensure joints with excellent mechanical characteristics and resistance to pressure and vibrations. Fluidity Excellent capillary penetration capacity Excellent mechanical characteristics

Other elements

COPPER PHOSPHORUS AND COPPER PHOSPHORUS SILVER ALLOYS They are successfully and widely used in sanitary piping systems because, not containing zinc, they do not incur the risk of “dezincification”. The presence of phosphorus greatly helps to reduce the formation of oxides during the heating and brazing process. The addition of silver, in addition to phosphorus, guarantees a better mechanical resistance of the joint (especially in tensile stress), these alloys cause a slight loss of wettability during brazing. Brazing of these alloys is carried out through rapid heating with a torch thanks...

Other elements International Norms

BRASS ALLOYS Brazing with brass alloys, because of its high atomic-scattering capacity, is used for the characteristic of being better able to conceal the brazing itself and therefore improve the aesthetic appearance of the joint, a joint which is hidden from view. It is therefore particularly appreciated when making brass furniture or brass display accessories. Joint aesthetics Other elements Solidus -liquidus range

ALUMINIUM ALLOYS These alloys are suitable for brazing aluminum with other materials. They find their main application in the sectors of refrigeration and air-conditioning, automotive and the hobby sector. Aluminium brazing Composition % Product International Norms

TRIFOILS TRI-TECH Tri-Tech is the ideal product for the brazing of hard metals, especially when brazing the teeth of saws. Tri-Tech is produced by the coupling of two sheets of silver alloys with a copper sheet in the centre, which thanks to particular technology and a specific very high pressure lamination, permits the coupling of the three sheets until a single layer is obtained. The final product allows the brazing of hard metals which satisfies all the requirements of sealing and mechanical and shock resistance needed, characteristics essential for the applications for which the tool is...
