Used for brazing of aluminum and its alloys (Max 1.5% Mg / Max 1% Si) and dissimilar joining of aluminum – stainless steel.
Used primarily with gas-oxygen torches (flame) but also in selected induction and furnace heat brazing application.
Activity range 500 - 650°C.
Description and Flux characteristics:
Flxal is active chloride-fluoride based aluminum brazing powder flux.
Most suitable for brazing of radiators, air conditioning, household appliances, electrical appliances, electrical heating systems and transformer bus bar.
Used neutral to slightly carburizing flame.
Leaves water soluble (corrosive) flux residues.
General information:
Based on specification: EN1045 FL10. * For use with AL4047 (12% silicon) aluminum filler alloy.
Flux removal: Flux residues left by this flux are corrosive and must be removed from brazed joint area. After brazing clean flux residues by dipping in dilute nitric acid followed by cold water rinse and then hot water rinse.
