Abstract

Provided is an aluminum alloy structure comprising one member to be joined and another member to be joined that are thermally joined together. The one member to be joined comprises 1.80 to 3.00 mass % of Si, 0.10 to 1.60 mass % of Mn, and 0.01 to 0.70 mass % of Fe, with the balance being Al and unavoidable impurities. An average grain size is 200 µm or less in an outermost layer of the one member to be joined in a joined part between the one member to be joined and the other member to be joined. An average grain size is 400 µm or more in a section at a position with a depth of 100 µm of a part having the smallest wall thickness of the one member to be joined. The present invention can provide an aluminum alloy structure, and an aluminum alloy extruded material and a method for producing the same that can simplify manufacturing processes because of being joinable with a single layer, the aluminum alloy structure, and the aluminum alloy extruded material and the method for manufacturing the same having good joining performance and being capable of inhibiting deformation during thermal joining.
