Applications Flux Pastes are mainly used inside B-tubes and folded tubes, in order to provide a line of flux on a cladded surface. These paste formulations are available in FG (fine grade) version, the N version (“new” – i.e. with adjusted rheology and re-mixing characteristics) and UV version (ultraviolet sensitive pigments for special application monitoring). Metalized Flux Pastes (Brazing […]
Solvay is exhibiting on the Chillventa in Nuremberg. Visit our stand in hall 8, no. 8-416. The specialists from the NOCOLOK® Team for aluminium brazing are onsite and looking forward to your visit. The Chillventa shows innovation & trends from the energy efficiency – heat pumps – refrigeration sector in Nuremberg from 11 – 13 October 2016. Opening […]
In Myths about Aluminium Brazing Fluxes Part 1 we reported about the rumor that fluxes with a lower melting range are superior. Now we take a look to another Myths about Aluminium Brazing: Myth – A Flux with Smaller Particle Size is More “ACTIVE” and Leaves Less Flux Residue Some rumours have been spread that a […]
Myth – Fluxes With a Lower Melting Range are Superior There are claims that a lower melting point flux is better for brazing (i.e. melting between 550 and 560°C – approximately 10 – 15°C below conventional fluxes). The idea here is to try to fool the engineer by illustrating the merits of “early” flux melting, […]

Looking for alternatives of a standard aluminium brazing process with a lower level of nitrogen consumption or you are involved in the process of heat exchangers manufacturing, especially in the automotive and aftermarket, don’t miss the Webinar. SECO/WARWICK guarantee a high quality of brazing process of elements, especially for unique types of aluminium heat exchangers. […]
What is critical Have a clean surface (free of dust, grease) Heat the joint evenly to brazing Temperature Choose the right brazing alloy for the job (Mg content !) Select the appropriate flux to remove the oxide skin from the faying surfaces of the joint Use a capillary gap of the appropriate size ALUMINIUM BRAZING […]
