ABSTRACT:
Method of brazing aluminum or aluminum alloy parts, using a flux which is made from an eutectic of BaCl.sub.2, NaCl, and KCl as a base, and one or more of fluorides as an activating agent. On account of the flux being not deliquescent, the brazing method can be carried in an atmosphere which is free from oxygen. Flux residues are easily removable in this invention.
