Used for welding of aluminum and (Aluminum – Mg & Aluminum – Si) its alloys.
Versatile flux used primarily with gas-oxygen torches (flame) but also in selected induction and furnace application.
Activity range: 550 - 650°C.
Description and Flux characteristics:
Alubraze is all purpose chloride-fluoride based powder flux for brazing / welding of sheet and cast aluminum.
It dissolves all oxide coated on base metal, eliminate porosity and promotes strong joint.
Leaves water soluble (corrosive) flux residues.
General information:
Based on specification: AWS A5.31 M: FB1 –A. *For use with AL1188 (pure aluminum), AL4043 (5% Silicon) and AL5356 (5% Magnesium) group aluminum filler alloys.
Flux removal: Flux residues left by this flux are corrosive and must be removed from weld/brazed joint area. After welding / brazing clean flux residues by dipping in dilute nitric acid followed by cold water rinse then hot water rinse.
