Summary:PROBLEM TO BE SOLVED: To provide a manufacturing method of alminum tube combined flange member which forms a combined blank of more similar to an article shape than the conventional one, which reduces the process number and which improves the production efficiency in the producing method where two kinds of aluminum alloy members are extruded and the aluminum tube combined flange member is obtained. SOLUTION: A columnar body 3 composed of A3033 material M2 is inserted and filled in a hollow part of a tubular body 2 composed of A7N01 material M1 two layer composition billet 1 is formed, this billet 1 is hot-extruded with an indirect extrusion press 6 by using a die 7 on which plural numbers of die holes 7a of the cross-section shape corresponding to the plane shape of an article flange 11 are installed in a same interval on a concentric circle, a plural number of combined blanks 4 made as one body pressed forcibly in contact with two kinds of aluminum alloy materials in the cross-sectional direction are formed at the same time, next this combined blank 4 is cut by the length corresponding to the thickness of the article flange 11 and a combined member 5 is made individually.
