Abstract:
An aluminum alloy extruded material having chemical composition that includes Cu by 2.5 to 3.3%, Mg by 1.3 to 2.5%, Ni by 0.50 to 1.3%, Fe by 0.50 to 1.5%, Mn by less than 0.50%, Si by 0.15 to 0.40%, Zr by 0.06 to 0.20%, and Ti by less than 0.05% in mass percentage, and the remaining part that includes Al and inevitable impurities. On a cross-section of the aluminum alloy extruded material, a grain diameter of an intermetallic compound is 20μm or less in equivalent circle diameter; density of an intermetallic compound, whose grain diameter is 0.3 to 20μm in equivalent circle diameter, is 5×10 3  piece/mm 2  or more; and, an average grain diameter of sub-crystal grains is 20μm or less in equivalent circle diameter.

Claim (Index 1):
An aluminum alloy extruded material, comprising:\n chemical composition that comprises\n Cu by 2.5 to 3.3%, Mg by 1.3 to 2.5%, Ni by 0.50 to 1.3%, Fe by 0.50 to 1.5%, Mn by less than 0.50%, Si by 0.15 to 0.40%, Zr by 0.06 to 0.20%, and Ti by less than 0.05% in mass percentage, and \n a remaining part that comprises Al and inevitable impurities, \n wherein, on a cross-section of the aluminum alloy extruded material, a grain diameter of an intermetallic compound is 20 \u03bcm or less in equivalent circle diameter; density of an intermetallic compound whose grain diameter is 0.3 to 20 \u03bcm in equivalent circle diameter is 5\u00d710 3  piece/mm 2  or more; and, an average grain diameter of sub-crystal grains is 20 \u03bcm or less in equivalent circle diameter.
