Silicon for aluminium brazing

Silicon: a key element for enhanced aluminium brazing and great bonding

Aluminium Brazing is an advanced process used to produce high performance

heat exchangers, radiators, evaporators, and condensers in the automotive industry, in particular in new generation hybrid and electrical vehicles. It is also used for non-automotive applications, such as air conditioning and refrigeration.

Aluminium brazing joins metal parts using torchwork with a nonferrous flux using gas, heated to a much lower temperature (400°C) than that used in traditional soldering This means that brazing offers significant advantages over gas welding: it uses less energy, the brazing filler is more fluid (flowing by capillary action), is quicker to achieve a strong bond and produce a smoother and better-looking finish.
