The objective of the present invention is to provide a method of manufacturing an aluminum structure including a hollow structure and a tubular member, with which it is possible for robust fillets to be formed easily on the outer surface of the hollow structure. A clad plate is prepared. The clad plate has a multi-layer construction comprising two or more layers including a core layer formed from an aluminum material and a brazing material layer disposed on one surface side of the core layer, wherein an element that breaks down oxide films is included in at least one layer in the multi-layer construction. A tubular member (3) comprising an aluminum material is prepared. A hollow structure (20) of which the outer surface side is formed from a brazing material layer, and which has a through-hole (211) into which the tubular member (3) is inserted is fabricated from the clad plate. The tubular member (3) is inserted into the through-hole (211) to assemble an aluminum structure (1) in which the end portion of the tubular member (3) is disposed inside the hollow structure (20). The aluminum structure (1) is heated in an inert gas atmosphere, thereby brazing the hollow structure (20) to the tubular member (3) by means of the brazing material layer in the clad plate. |
