Air furnace brazing and bonding of light alloys

CHARACTERISTICS - PHYSICO-CHEMICAL PROPERTIES, COMPOUND ELEMENTS

Composition : alkaline-muddy chlorides and fluorides.

APPLICATION FIELD

• USERS
  Automotive and aircraft OEM for the manufacture of silicon cladded aluminium heat exchangers through an air furnace.
• APPLICATION FIELD
  Furnace brazing : Aluminium and silicon clad aluminium (7 to 12%). Brazing temperature : from 530 to 640° C.

DIRECTIONS FOR USE, USING ADVICE, COMMON USING CONCENTRATION

Preparation of the flux : Mix 2/3 flux with 1/3 water and stir vigorously. The reaction For large quantities, the preparation tank must be thermally controlled. A thin and stable suspension is obtained, which must be stirred continuously. Parameters to be controlled :

• Temperature during preparation
• Concentration, density, viscosity, stability (sedimentation time)
