Soldering of Aluminum

    ELSOLD® Al-S lead-free flux cored solder wires now offer the possibility for direct soldering ofAluminum alloys and further difficult to solder materials - without special pretreatments or any special equipment.

    This makes direct changing form Copper to Aluminum much easier, using the existing processes and tools. For the first time, due to the innovative composition and new developed production processes the ELSOLD® Al-S flux offers both a good and fast wetting and an improved corrosion behavior, which is normally the most critical point of soldered Aluminum joints due to the electrochemical potentials of the different metals and the high aggressively of the fluxes. ELSOLD® Al-P offers best solutions for soldering Aluminum alloys, which need a very high activity, in different soldering processes.
