Aluminum alloy plate for automobile and manufacturing method thereof |
摘要 |
An aluminum alloy plate for an automobile has a chemical composition containing 0.8 to 1.5% by mass of Si, 0.4 to 0.7% by mass of Mg and 0.5 to 0.8% by mass of Cu. The crystal grain size is 10 to 40 mum. Cu content obtained by analyzing the outermost surface of the aluminum alloy with an oxide film according to X-ray photoelectron spectroscopy (XPS) is {fraction (1/10)} to ½ of the Cu content of the bulk of the aluminum alloy plate.
