Donau Aluminiumlot

Special solder wire (alloy SN 97 % / CU 3 % according to DIN EN 29453) for soft soldering of aluminium and aluminium alloys, also with copper. The flux is characterised by optimum wetting on aluminium. Flux content: 4.0 % according to DIN EN 29454, 2.1.2.C. Flux distribution: 1-segmented. Diameter in mm: 1.50. Processing information: The flux contained is very temperature-sensitive and must not be overheated. The maximum workpiece temperature is 300 °C. The recommended soldering iron temperature should not exceed 350 °C. We recommend indirect heating of the solder wire via the workpiece or processing with a soldering iron. For large-volume workpieces, we recommend preheating the parts to be soldered up to 250 °C. Washing: The flux residues are corrosive and must be thoroughly removed with water after soldering.
