SWP 7520 500g tub aluminium gas welding flux

Product information

SWP Aluminium Welding Flux is used for welding aluminium metal in sheet, extruded and cast form. The flux is an excellent solvent for aluminium oxide, promoting strong joints free of oxide inclusions. This aluminium welding flux is formulated for welding 52-S, as well as the pure 2-S aluminium sheet used in aircraft.  The flux works best with oxy-acetylene gas torches using an aluminium filler rod

To remove flux residues after use, immerse the workpiece in a 10-20% strength mix of caustic soda
