Abstract
A novel flux is provided for use in the low-temperature brazing aluminum materials of varied compositions, the flux being composed of a KCl--NaCl--BaCl.sub.2 base and 0.5-5.0 wt. % of LiF and/or 1.0-10.0 wt. % of ZnCl.sub.2 added to the base. A method of flux brazing a low-melting aluminum material is also provided, and the method is carried out by applying such a novel flux as well as a low-melting brazing agent to the aluminum material portions to be adjoined. The brazing agent is composed of an Al--Si--Zn alloy which contains 3-12% by weight of Si and 15-70% by weight of Zn.
