Abstract

See full text

An aluminum alloy material is welded by performing friction stir welding to form a welded section in an aluminum alloy welded component. The aluminum alloy material contains Mg: 0.3-6.0% (mass %, hereinafter the same), Cu: 0.2% or less, Si: 0.1% or less, Fe: 0.1% or less, the balance being Al and inevitable impurities. Second phase particles dispersed in the aluminum alloy material have a grain size of 5 μm or less as observed with an optical microscopic. Because the second phase particles are homogeneously dispersed in a welded section equivalent portion of the aluminum alloy welded component as compared to other portions, variations in pit formation caused by etching during anodizing are reduced, thereby eliminating color tone variations in the anodized coating formed on the aluminum alloy welded component.
