A method of brazing an aluminum material, which contains: using an aluminum alloy brazing sheet, wherein an aluminum alloy containing 0.2 to 1 mass % of Mg is used for a core alloy; the brazing sheet, in which an Mg amount in a filler alloy is 0.05 mass % or less, is used; and the brazing is carried out by using a brazing furnace that has at least two chambers for brazing in an inert gas atmosphere under a heating condition of a temperature-rising time of within 12 minutes from a temperature exceeding 200° C., to 570° C.; a brazing furnace and an aluminum alloy brazing sheet, each of which is used in the method; and a heat exchanger, which is produced by the method.
