Title (EN) RESIN-COATED ALUMINUM ALLOY SHEET FOR DRAWN AND IRONED CAN
(FR) FEUILLE D'ALLIAGE D'ALUMINIUM REVETUE DE RESINE, POUR DES BOITES ETIREES ET A PAROIS REDUITES
Abstract:
(EN) A resin-coated aluminum alloy sheet which makes it possible to form drawn and ironed cans having strengths necessary for suppressing the breakage of the walls when complicated machining inclusive of bending and unbending at a die shoulder radius portion having a small shoulder radius and subsequent ironing are carried out as a dry process, and which can provide an aluminum alloy film having a sufficient adhesive strength after the machining. The sheet is characterized by being manufactured by applying a silane treatment using a silane coupling agent alone or a composite treatment using both chromium phosphate and a silane coupling agent to an aluminum alloy sheet whose contents of Mn, Mg, Si, Cu, Fe and (Si+Fe), thickness and yield strength are controlled to be in predetermined ranges, and then coating the sheet with a thermoplastic resin.
(FR) L'invention concerne une feuille d'alliage d'aluminium, revêtue de résine, qui permet de former des boîtes étirées et rectifiées. Ces boîtes présentent une résistance qui permet de supprimer la rupture des parois observées lors d'opérations d'usinage complexes, parmi lesquelles le cintrage et le décintrage, au niveau d'une partie d'épaulement de matrice présentant un rayon inférieur, suivies de la réduction de parois, dans le cadre d'un procédé à sec. Cette feuille permet d'obtenir un film d'alliage d'aluminium présentant une résistance adhésive suffisante après l'usinage. Le procédé selon l'invention consiste à fabriquer une feuille en appliquant un traitement de silane, à l'aide d'un agent de couplage de silane seul, ou d'un traitement composite, avec du phosphate de chrome et un agent de couplage de silane, sur une feuille d'alliage d'aluminium dont les teneurs en Mn, Mg, Si, Ci, Fe et (Si+Fe), l'épaisseur et la limite d'élasticité sont contrôlées dans des plages prédéterminées, puis à recouvrir cette feuille d'une résine thermoplastique
