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 technology used for the production allows the elimination of any type of binder with the result of obtaining a joint cleaner and no emission of harmful fumes due to their combustion.
Characteristics: seamless AlSi12 flux-cored wire with a non-corrosive neutral flux powder. The seamless flux-cored pipe type design offers highest and stable brazing quality avoiding any risk of leakage of the flux in the environment providing the right amount of it at any time to get a sound joint. The wire can be used also to produce preformed.
Application: extremely fluid and smooth alloy, with considerable capacity of penetration by capillarity, used for flame-brazing and induction-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 with automatic wire feeding machine.
