Abstract:
It is an object to provide an aluminum alloy forged material for an automobile excellent in tensile strength while maintaining excellent corrosion resistance, and a method for manufacturing the same. Provided are the aluminum alloy forged material for an automobile and a method for manufacturing the same, the aluminum alloy forged material being composed of an aluminum alloy including Si: 0.7-1.5 mass %, Fe: 0.1-0.5 mass %, Mg: 0.6-1.2 mass %, Ti: 0.01-0.1 mass % and Mn: 0.3-1.0 mass %, further including at least one element selected from Cr: 0.1-0.4 mass % and Zr: 0.01-0.2 mass %, restricting Cu: 0.1 mass % or less and Zn: 0.05 mass % or less, and a hydrogen amount: 0.25 ml/100 g-Al or less, the remainder being Al and unavoidable impurities, in which the depth of recrystallization from the surface is 5 mm or less.
