Abstract
(EN)
The purpose of the present invention is to provide an aluminum member that is obtained by simpler primary treatment than in the past and that has high whiteness and suppressed unevenness of white color, and a method for producing the same. The aluminum member according to the present invention has a base material made of aluminum or an aluminum alloy, and an anodized film on the surface of the base material. The aluminum member, measured from the anodized-film-surface side, has an arithmetic average roughness Ra of 0.1 μm or higher, a roughness curve element average length RSm of 10 μm or less, and a Hunter whiteness of 60-90.

L'objectif de la présente invention est de fournir un élément en aluminium qui est obtenu par un traitement primaire plus simple que dans le passé et qui présente une blancheur élevée et une irrégularité de la couleur blanche supprimée, et son procédé de production. Selon la présente invention, l'élément en aluminium comprend: un matériau de base qui est formé d'aluminium ou d'un alliage d'aluminium; et un film anodisé sur la surface du matériau de base. L'élément en aluminium, mesuré à partir du côté de la surface de film anodisé, a une rugosité moyenne arithmétique Ra de 0,1 µm ou plus, une longueur moyenne d'élément de courbe de rugosité RSm de 10 µm ou moins, et une blancheur de Hunter de 60-90.
