Aluminum Brazing / Gas Welding Fluxes

Flux selection is determined by the base metal and the filler metal alloys working temperature. The working temperature and melting range of the filler alloy must match the flux's active range.

Aluweld Flux Powder
	Recommended for:	Description and Flux characteristics:	General information:
	Used for welding of Aluminum and its alloys. Used with pure aluminum filler rod. Use full fusion technique with neutral flame. Activity range: 550 - 650°C.	BAlweld is gas welding powder flux. Suitable for joining of pure aluminum castings not containing zinc. Leaves water soluble (corrosive) flux residues. High activity with good fluidity.	Based on specification: AWS A5.31 M: FB1-A. *For use with AL1188( pure aluminum) filler rod. 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 a hot water rince. Standard packing: 500gms.

Alubraze Flux Powder
	Recommended for:	Description and Flux characteristics:	General information:
	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.	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.	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. Standard packing: 500gms, 20kg.

Flxal Flux Powder
	Recommended for:	Description and Flux characteristics:	General information:
	Used for brazing of aluminum and its alloys (Max 1.5%Mg / Max 1% Si) and dissimilar joining of aluminum – stainless steel. Used with primarily with gas-oxygen torches (flame) but also in selected induction and furnace heat brazing application. Activity range 500 - 650°C.	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.	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. Standard packing: 250gms,500gms.

Flxal – L Flux Powder
	Recommended for:	Description and Flux characteristics:	General information:
	Used for brazing of aluminum and its alloys (Max 1.5%Mg / Max 1% Si). Used with Flame and selected induction brazing systems. Activity range: 450 - 600°C.	Flxal – L is a active chloride –fluoride based low temperature powder brazing flux. Excellent capillary and fluidity at very low melting point. Insures complete spread of brazing alloy in and around the joint. Leaves water soluble (corrosive) flux residues.	Based on specification: Proprietary flux formulation.*For use with AL4047(12%silicon), AL4045(10% silicon), AL4145( 9 to 11% silicon and 3 to 5% Cu) aluminum filler alloys. 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 rinse and then hot water rinse. Standard packing: 250gms, 500gms.
