摘要： A method of producing a high-intensity aluminum alloy extruded material excellent in resistance to stress corrosion cracking, the method comprising: preparing an Al—Zn—Mg-based aluminum alloy, subjecting the aluminum alloy to extrusion so that a temperature of an extruded material obtained immediately after the extrusion is 440° C. or more; allowing the extruded material to cool in an air at a cooling rate of less than 100° C./min until the temperature range of the extruded material reaches 300 to 400° C. from immediately after the extrusion for one minute to 3 minutes and 24 seconds; and then forced cooling the extruded material at a cooling rate of 100 to 2000° C./min until the temperature of the extruded material reaches 150° C. or less, followed by an aging treatment.
