A non-corrosive, non-hygroscopic silver brazing flux compound. In the preferred embodiment, the flux compound consists of potassium fluoroborate approximately 26% by weight, boric acid approximately 26% by weight, potassium bifluoride approximately 24% by weight, potassium tetraborate approximately 20% by weight, and potassium carbonate approximately 3.5% by weight. The method of making the flux compound and its non-corrosive and non-hygroscopic properties enables the flux compound to be especially suitable for use as either as a flux paste or dried and milled into a powder to be dispensed within a sheath of silver based filler material to form a flux cored brazing wire. |
