Anti-Borax No. 8 Aluminum Welding Flux is used for welding aluminum metal in sheet, extruded and cast form. The flux is an excellent solvent for aluminum oxide, promoting strong joints free of oxide inclusions. This aluminum welding flux is formulated for welding 52-S, as well as the pure 2-S aluminum sheet used in aircraft.  The flux works best with oxy-acetylene gas torches using 1100-series aluminum filler rod. It works well in selected induction and furnace applications.
