The present invention relates to a manufacturing method of an aluminum alloy product, which comprises the steps of: extruding an aluminum alloy billet and manufacturing an aluminum extruded object having a connection portion; winding the aluminum extruded object having the connection portion; thermally treating the aluminum extruded object which is wound; linearly correcting the aluminum extruded object which is wound; and correctly cutting the aluminum extruded object which is linearly corrected. As the aluminum extruded object is wound to perform heat treatment in a following process, it is unnecessary to cut the aluminum extruded object to a predetermined size in advance. Thus, a continuous process can be performed when an aluminum alloy product is manufactured. |
