Aluminum alloy member |
摘要 |
An aluminum alloy member including a sheet-like aluminum alloy member having ends joined by friction stir welding, and forming an anodic oxidation coating on a weld front surface or a weld back surface, the aluminum alloy member including 0.3 to 1.5 mass % of Mg, 0.2 to 1.2 mass % of Si, 0.5 mass % or less of Cu, and 0.2 mass % or less of Fe, with the balance being Al and unavoidable impurities, Fe-containing second phase particles having a particle size (circle equivalent diameter) of more than 1 μm, among second phase particles dispersed in a matrix of the aluminum alloy member, having an average particle size of 5 μm or less. |

1. An aluminum alloy member comprising an aluminum alloy sheet having ends joined by friction stir welding, a weld front surface or a weld back surface being anodically oxidized, the aluminum alloy member further comprising 0.3-1.5 mass % of Mg, 0.2-1.2 mass % of Si, no more than 0.5 mass % of Cu, no more than 0.2 mass % of Fe, with the balance being Al and unavoidable impurities and Fe-containing second phase particles having a particle size of more than 1 μm among second phase particles disposed in a matrix of the aluminum alloy member having an average particle size of no more than 5 μm, wherein the weld front surface is a weld surface into which a rotating pin is inserted during friction stir welding and the weld back surface is a surface opposite to the weld front surface. |
