摘要： The present invention provides an aluminum alloy component having an anodic oxide film less causing cracks and high in surface smoothness, which is capable of reducing abrasion of a cutting tool regardless of the excellent machinability. The aluminum alloy component (1) has an anodic oxide film formed on a surface of a base metal of an aluminum alloy. The aluminum alloy consists of Fe: 0.5 to 2 mass %, Cu: 0.35 to 0.6 mass %, Mg: 0.35 to 1.3 mass %, Si: 0.2 to 1.3 mass %, Cr: 0.005 to 0.3 mass %, Mn: 0.01 to 0.3 mass %, Ti: 0.005 to 0.1 mass %, and the balance being inevitable impurities, wherein Zn is controlled to be less than 0.25 mass %, and wherein Al—Fe series crystals and Al—Fe—Si series crystals having a maximum grain diameter of 30 μm or less exist in the anodic oxide film in a dispersed manner with an average center-to-center distance of 10 to 100 μm, and a percentage of a total occupied area of the Al—Fe series crystals and Al—Fe—Si series crystals in the anodic oxide film is 5% or more.
