Abstract

La présente invention concerne le domaine de la métallurgie et concerne en particulier un matériau en alliage d'aluminium et son procédé de fabrication. Le matériau comprend : 0,3 à 1,0 % en poids de Si, 0,2 à 0,6 % en poids de Mn, 0,15 à 0,2 % en poids de Ti, 0,01 à 0,01 % en poids de Ca, 0,1 à 0,3 % en poids de Cu, 1,56 à 2,38 % en poids de Mg, et le reste étant de l'Al et des impuretés inévitables. L'addition contrôlée de Ti et de Si améliore la limite d'élasticité, le procédé de trempe alternée à l'eau-l'air améliore la rigidité, et le dopage de Mg augmente la performance de conductivité thermique. Ainsi, tout en assurant la conductivité thermique, la rigidité, la limite d'élasticité et la résistance à la traction de l'alliage d'aluminium sont améliorées.
