IMPROVED ATMOSPHERIC-PRESSURE ALUMINIUM BRAZING METHOD

摘要

The present invention relates to an aluminium brazing method conducted in an atmospheric-pressure furnace, which is characterized by the implementation of the following operational conditions: i) the filler alloy used is an alloy obtained by mechanical synthesis, comprising aluminium, silicon, nickel and optionally magnesium or other alloying elements, such as copper, zinc, silver, chromium and titanium; j) the oxygen content in the furnace is less than a few ppm, preferably less than 1 ppm and that the dew point in the furnace is below -30°C, preferably below -40°C and even more preferably still below -45°C.
