Definitions

  • a particularly advantageous embodiment of the invention consists of manufacturing heat exchangers, especially for radiators.
  • a brazing alloy made of aluminum-silicon the process is as follows the stainless steel part (5) are first degreased and then submitted to a chemical pickling into an aqueous bath which can be an acid or alkaline bath but is preferably an acid bath, the composition thereof, can, for example, be as follows nitric acid 0.1 1 sodium fluoride g water 0.8 l
  • the pickling in a bath having the composition as shown above as an example requires an immersion into the bath for a duration of about 10 run, while the bath is kept at a temperature of about C.
  • the immersion duration can of course vary according to the bath acidity and also according to the temperature thereof. However the above duration and temperature have been considered particularly suitable for a pickling in the usual conditions of industrial processing.
  • the invention is not restricted to the embodiment shown as an example, for various modifications thereof can moreover be applied to it without departing from the scope of the invention.
  • Especially the aluminum parts with or without a coating of brazing alloys can also be treated to be covered with a zinc containing coating thus avoiding an oxid formation on their surface after pickling.
