Fluxes are for silver brazing, phos/copper brazing, solder, and aluminum. These fluxes are formulated to be dispensed automatically through Fusion applicators. ![]() With paste alloys, the flux is built into the mixture along with metal alloys in powder form.įusion also has homogeneous dispensable fluxes to use with wire, rings, and preform alloys. When used with solid forms of brazing and soldering alloy, fluxes are generally applied by brushing, dipping, or spraying the parts before heating. ![]() Fluxes are matched to the temperature range of the filler metals that they are paired with. Flux residues are normally removed after brazing and soldering to prevent damage to the joint. Solder fluxes may be classified into one of the following groups:įluxes consist of mild organic acid or strong inorganic acid which promotes high speed cleaning of metals with strong surface oxides. Brazing fluxes are generally of a highly corrosive nature. Fluxes are a material which, when heated, serve to remove and exclude surface oxides from the base metal.
