ABSTRACT:
A brazing paste for aluminum or aluminum alloy parts. The paste consists essentially of, by weight, between about 8 and 72 percent potassium tetrafluoroaluminate having a purity of at least about 96 percent, between about 15 and 75 percent aluminum-silicon alloy, and between about 2.5 and 50 percent organic carrier having a vaporization temperature which is below the melting temperature of the aluminum-silicon alloy, and the melting temperature of the potassium tetrafluoroaluminate being below the melting temperature of the aluminum-silicon alloy. The high purity potassium tetrafluoroaluminate has a lower melting temperature so that a greater number of aluminum-silicon alloys may be used therewith and does not have corrosive substances so that the braze can be of high quality and not require additional steps of washing and drying the brazed part for overall cost savings.
