Abstract
A method for brazing aluminum alloy-assembled articles with a filler alloy having a liquidus temperature of 540° C. or lower and a difference of temperature between the liquidus temperature and the solidus temperature being 100° C. or lower, wherein the highest temperature reached in the assembled article at the time of heating for brazing being set 40° C. or more higher than the liquidus temperature but 585° C. or lower. An aluminum alloy-filler alloy usable at low temperature for brazing, which comprises Si in an amount of 4.0 wt % to 8.0 wt %, Zn in an amount of 7.0 wt % to 20.0 wt % and Cu in an amount of 10.0 wt % to 35.0 wt %, with the balance being made of aluminum.
