APPLICATIONS

Brazing alloy recommended for its penetration and wettability. Highly appreciated in repair of capillary losses of welded joints and in situations where the melting point represents a critical point (thanks to its low working temperature). To be used for welding joints with interference between 0,02 mm and 0,06 mm. It can be safely used without the addition of deoxidizer, since it is alloyed copper-phosphorus. In any case, if the type of application so requires, the deoxidizer FCU is recommended. Not suitable for applications in contact with sulfides. Not suitable for Fe and Ni alloys.
