Summary The article was written on the basis of frequently asked questions from companies which either wanted to start a new all-aluminium brazing production of heat exchangers or wanted to convert from copper and aluminium mechanical assembly design to all-aluminium brazed parts. The questions were grouped into three main categories: Equipment (emphasis on assembling process), […]
Solvay Fluor is taking part at the Schweißen & Schneiden 2013 and present two main topic at the show at hall 11, stand A123: NOCOLOK Aluminium Brazing Fluxes Solvay Fluor is the leading pioneer for aluminium brazing – and has been for years. With our revolutionary NOCOLOK Flux we are the global market leader and […]

The NOCOLOK dictionary was the reference book for the brazing of aluminium at its release over a decade ago. Now it has been completely revised and published under the name NOCOLOK Encyclopedia, with many additional chapters including a chapter on special fluxes. Within the new, fresh and tidier design lies concentrated knowledge for technicians and […]
In a flux delivery system, the distances that the flux slurry has to travel is often very short and there is no time for the flux slurry to settle out in the lines or header pipe of the nozzle array. However, if the flux slurry must be conveyed over long distances, to the waste water […]
In recent years, the topic of what to do with wastewater from fluxing operations has gained a lot of attention in light of heightened environmental awareness and compliance. Years ago, wastewater from cleaning slurry booths, waste flux slurries etc. were simply diluted and dumped down the drain. Some manufacturers are still following this practice, but […]
Selective Pre-Fluxing with Adhesives – Fashion or Progress Summary Over the last 15 years, selective prefluxing – also called paint fluxing or binderbased fluxing – has evolved as an alternative method for applying flux powder in the aluminium brazing industry. There are many activities to define process parameters of fluxing with adhesives. The first part […]
Dumping With continuous use, a flux slurry will eventually become contaminated. So far, there is no data that correlates the level of accumulated contaminants with poor brazing. Therefore, it is better to be on the safe side rather than wait till the number of rejects rise due to a contaminated or dirty slurry. It is […]
