PROBLEM TO BE SOLVED: To provide a method of brazing aluminum material having excellent fillet forming ability equal to or higher than a conventional brazing method using a fluoride flux and capable of using a bonded member consisting of an Mg added aluminum alloy effective for thinning and strength enhancement.SOLUTION: In the method of brazing aluminum material of bonding a brazed member 4 consisting of the aluminum material by brazing it with an Al-Mg-Si based brazing filler metal 3 containing Mg of 0.2-5.0% and Si of 3-13% in mass%, the excellent fillet forming ability is obtained by performing brazing with the Al-Mg-Si based brazing filler metal 3 by arranging a composition 5 containing a silicon compound which is liquefied at normal temperature at least on a bonded part surface 4a of the brazed member 4, and use of the bonded member consisting of an Mg added aluminum alloy effective for thinning and strength enhancement is allowed by not using the fluoride flux. |
