Choice of flux depends on the joining materials and operating temperature of the alloy. Flux must melt and become active at a temperature lower than that of the melting point of the alloy. Flux should remain active during the whole brazing process, removing the oxides from the two joining metals or preventing the oxidation.
Flux residue removal:
Flux residues soluble in water can be removed by immersion in water followed by brushing in a stream of water. For faster removal 5-10% sulphuric acid solution can be used followed by brushing in a stream of water.
For removing flux residues insoluble in water immersion in a warm 10% sodium hydroxide solution followed by brushing in a stream of water is recommended.
