本発明は自然発色用Ａ１合金に関し、さらに詳しくは、
陽極酸化処理により黄色系の着色皮膜を生しる自然発色
用Ａ１合金に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an A1 alloy for natural color development, and more specifically,
This invention relates to a naturally colored A1 alloy that produces a yellowish colored film through anodizing treatment.

％とする。Fe is an essential element for obtaining an anodic oxide film with a desired color tone. If the content is less than 0.4%, a yellow colored film will be produced, and if it is contained in excess of 2%, the color will change. It becomes easier to hide unevenness. Therefore. 1・゛Q content is 0.4-2

! With i'C, a yellow coloring film was not obtained, and 1%
If the content exceeds 100%, the strength will increase. Therefore, (It
The content of ridges is 0.05 to 1%.
さらに、ＡＩ、ＦｅおよびＣｒ固溶木が含有されている
