Zusammenfassung:PROBLEM TO BE SOLVED: To provide an aluminum material which is given design properties and exhibits independent coarse recrystallized grains in a matrix composed of fine recrystallized grains by performing suitable treatment, and to provide a method for producing the same. SOLUTION: A plastically worked material of an aluminum alloy ingot having a composition comprising, by weight, 0.8 to 5.0% Mg, 0.15 to 0.80% Mn+Cr, further 0.005 to 0.15% Ti or 0.005 to 0.15% Ti and 0.0005 to 0.05% B, and the balance Al is subjected to O material treatment, and thereafter, strain of 1 to 6% is applied thereto. The aluminum worked material with the strain applied thereto is held to the temperature range from T0°C to
