Abstract
Official abstract text for this publication.
An aluminum alloy material, containing Al, Mg, Si and Sn, where an oxide coating is formed on a surface of the aluminum alloy material, and when the oxide coating formed on the surface of the aluminum alloy material is subjected to glow discharge emission spectroscopic analysis, as the maximum value of each content of Sn and Mg for a region from the surface of the oxide coating to a depth where oxygen amount becomes 15 at %, a Sn content is within a range of 0.01-10 at %, and a Mg content is 0 at % or more and less than 10 at %.

1 . An aluminum alloy material, comprising: Al, Mg, Si and Sn, wherein an oxide coating is formed on a surface of the aluminum alloy material, and when the oxide coating formed on the surface of the aluminum alloy material is subjected to glow discharge emission spectroscopic analysis, as the maximum value of each content of Sn and Mg for a region from the surface of the oxide coating to a depth where oxygen amount becomes 15 at %, a Sn content is within a range of 0.01-10 at %, and a Mg content is 0 at % or more and less than 10 at %. 2 . The Al—Mg—Si-based aluminum alloy material according to claim 1 , wherein an adhesive layer is on a surface of the oxide coating that is formed on the surface of the aluminum alloy material. 3 . A joined body, comprising a plurality of the aluminum alloy materials according to claim 1 joined with each other through an adhesive layer so that the oxide coatings of the aluminum alloy materials oppose with each other. 4 . An automotive component, comprising the aluminum alloy material according to claim 2 . 5 . An automotive component, comprising the joined body according to claim 3 .
