AWS A5.10 ER 4043

EN/ISO 18273 SAL 4043

DIN 1732: SG-AL Si5



  • Repairing all brazable aluminum castings, filling in holes, building up worn or missing sections and joining cast to wrought parts.
  • General purpose outdoor use on repairing aluminum skids, platforms, loading docks, truck bodies, irrigation piping, fences and railings.
  • Joining thick to thin sections requiring a combination of braze-welding and brazing techniques.


  • Can both build up (bead form) or thin flow due to the specially designed orange flux coating.
  • Flux residue washes off easily with warm water.

Brazing Instructions

Brazing Techniques: Clean the surface and preheat heavy sections. Adjust the torch to a neutral to slightly carburizing mixture. Once piece is preheated simply allow a small amount of the flux coating to melt off the rod. When the flux flows out apply the alloy drop by drop, moving the torch constantly. Allow to cool and thoroughly remove all flux residues by scrubbing in warm water.

For thin flowing, adjust the torch to 3X carburizing and preheat to a higher temperature. Then touch the end of the rod to the work and continue heating, forcing the molten flux through the joint. Allow the rod to melt off and flow through the fluxed area. Keep the torch moving constantly.
