Abstract

L'invention concerne un procédé pour améliorer la réflectivité d'un élément d'aluminium ayant une réflectivité initiale inférieure à 75 pour-cent, qui consiste à nettoyer l'élément avec un premier agent de nettoyage, à sécher l'élément nettoyé, à réduire la rugosité d'au moins une surface de l'élément séché par électro-polissage ou par polissage chimique, à nettoyer ladite au moins une surface de l'élément avec un second agent de nettoyage, et à sécher ledit élément afin d'obtenir un élément ayant au moins une surface présentant une réflectivité finale supérieure à 80 pour-cent.
