Non corrosive and non hygroscopic flux powder to braze aluminium and its alloys with our Al Si 12alloy (AA 4047). Excellent for furnace brazing in a inert atmosphere with aluminium alloys with Mg < 0.4-0.5%, for induction brazing and also for flame brazing aluminium alloys up to 1.5% Mg content.
For furnace brazing can be applied like an aqueous slurry by flooding, spraying or dipping; the part must be dried before enter in the furnace. For best results with induction and flame brazing, the flux should be mixed with water and stirred to a creamy consistency. Heat until flux becomes liquid. No post brazing treatment are required.
