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 the <111> texture of 60% or more in a cross section parallel to the extrusion direction. |
