Suitable for the brazing of aluminium alloys. It requires no additional flux. Its application brings advantages in terms of productivity and reduction of brazing defects. It does not require to wash the joint after brazing because the flux residues are neutral and non-corrosive. The amount of flux inside the alloy can be varied according the particular application.

Characteristics: mixture of AlSi12 alloy powder and non-corrosive neutral flux powder, subsequently extruded to obtain wire, rods and preformed with the most various shapes.

Application: extremely fluid and smooth alloy, with considerable capacity of penetration by capillarity, used for flame-brazing, for induction-brazing and for furnace-brazing of the 1xxx, 3xxx e some 6xxx Aluminium alloys. Used mainly in the production of automotive components and in the industry of air conditioning and refrigeration.
