Applications
For soft soldering, e.g.:
Aluminum, aluminum alloys, copper and copper alloys (brass), unalloyed, low-alloyed and stainless steels, and joints of aluminum with copper, copper alloys and steels.

Typical application examples are
Components of electrical circuits, electrotechnical components, cables, pipes, filters, trim strips, sockets and floats. Cooling systems, metal goods, fittings.

Processing instructions
Clean soldering areas. Round off edges. Coat soldering surfaces with flux. Heat the tip of the soldering rod and dip it into the flux. Preheat the workpiece widely and continuously. Do not overheat. Remove corrosive flux residues.
Heat sources: Flame soldering (acetylene), flame soldering (propane/butane), soldering iron, resistance heating.
