Brazing of Aluminium Alloys with
Higher Magnesium Content using Non-Corrosive Fluxes – Part 1

Mar 26
2014

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

Making Fire from Water – The Safe Flame Project

Jan 21
2014

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

The Transition from Copper/Brass to Aluminium – Part 2

Dec 19
2013

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
