Technical Information by Leszek Orman, Hans-Walter Swidersky and Daniel Lauzon Abstract For just as long as aluminium has been used for brazing heat exchangers, there has been a trend to down-gauging components for weight savings. The most common alloying element to achieve higher strength alloys for the purpose of down-gauging is magnesium. While magnesium additions […]

DVS-TV was underway at the Schweißen & Schneiden tradefair in Essen, Germany, which took place in September 2013. The interesting video report is online since early February. Among other things, coverage included Solvay’s tradefair presence and the brazing demonstration with NOCOLOK Flux at the booth. Watch the video.
News from our partner: 8th International Congress Aluminium Brazing 03 – 05 June, 2014 – REGISTRATION Dear Sir or Madam! The 8th International Congress Aluminium Brazing will be again organised by DVS – German Welding Society respectively DVS Media GmbH. We cordially invite you to attend this 3-day-event, where expert authors will present papers about […]
Making fire from water is a seemingly insoluble contradiction – but in 2014 the project will hit the markets. Instead of propane or acetylene, hydrogen is burnt, which in turn is produced from water in an electrolyzer. Also, the oxygen for the combustion arises from the chemical decomposition. The portable unit requires a standard 220 […]
Technical Information by Daniel Lauzon Manufacturing Processes By the early nineties, aluminum had already almost completely replaced copper/brass in radiators at the Ford Motor Company. Ford had gone through mass production of mechanically assembled radiators starting in 1982 and introduced vacuum brazing in 1983. In 1989, Winterbottom reported, …”the manufacturing capability and the superior corrosion […]
Technical Information by Daniel Lauzon Synopsis The use of aluminum alloys in automotive heat exchanger applications has steadily increased over the nearly 3 decades, particularly in engine cooling and air conditioning systems for passenger vehicles. This paper will briefly review what precipitated the transition from traditional copper/brass to aluminum radiators by outlining the technical merits […]
1. Preparation and Application This article provides information about the application of binder systems for NOCOLOK Flux. Solvay offers three concepts for flux binder application: NOCOLOK Binder (water-soluble) / NOCOLOK Thickener (water-soluble) NOCOLOK System Binder (water-based) NOCOLOK Flux plus Binder Mixture (water-based) These products can be used in water-based NOCOLOK Flux slurries to improve flux […]
