Abstract:
An aluminum alloy extruded material in relation with the present invention is with high strength by die quench air cooling and excellent in SCC resistance. The aluminum alloy extruded material is an Al—Zn—Mg-based aluminum alloy extruded material for structural member for automobiles such as a bumper reinforce, a door guard bar and the like which satisfies three expressions of 5.0≤[Zn]≤7.0, [Zn]/5.38
