Aluminum alloy forged material for automobile and method for manufacturing the same

摘要

The aluminum alloy forged material for an automobile according to the present invention is composed of an aluminum alloy including Si: 0.7 - 1.5 mass%, Fe: 0.5 mass% or less, Cu: 0.1 - 0.6 mass%, Mg: 0.6 - 1.2 mass%, Ti: 0.01 - 0.1 mass% and Mn: 0.25 - 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 Zn: 0.05 mass% or less, and a hydrogen amount: 0.25 ml/100 g-Al or less, with the remainder being Al and inevitable impurities, wherein the aluminum alloy forged material has an area ratio of the <111> texture of 60 % or more in a cross section parallel to the extrusion direction.
