CATEGORY

Brazing

TYPE

Special eutectic Copper-Silver-Phosphor brazing alloy.

APPLICATIONS

Particularly recommended for sanitary and refrigerating installations, boilers, heat exchangers, tubing etc. Do not use in a sulphurous environment. For working temperatures up to 200ºC

PROPERTIES

Eutectic alloy self pickling on copper. Exceptional fluidity. It is very well suitable for the repair of the capillary losses of brazed joints with lower silver containing Phos-copper alloys. Ideal where the heat feeding is critical because of its low operating temperature.
