Title (EN) CLAD CAN STOCK
(FR) TÔLE REVÊTUE POUR CANETTES
Abstract:
(EN) Exemplary embodiments of the invention relate to a sheet article having opposed first and second surfaces, and having a core layer, a cladding layer at the first surface of the sheet article, and optionally a cladding layer at the second surface of the sheet article. The cladding layer at the first surface is made of an aluminum alloy selected from alloys AA3104, AA3004 and modified versions of alloys AA3104 and AA3004 additionally containing 1.0 to 2.0 wt% Fe and optionally up to 1 wt% Si. The core layer is an aluminum alloy having a yield strength and/or ductility greater than the yield strength and/or ductility of the alloy of the cladding layer at the first surface. The sheet article may be used as can body stock, can end stock or tab stock.
(FR) La présente invention concerne un article stratifié comportant deux surfaces opposées, ainsi qu'une couche de cœur, un revêtement au niveau de la première surface et éventuellement un revêtement au niveau de la deuxième surface. Le revêtement de la première surface est constitué d'un alliage d'aluminium choisi parmi les alliages AA3104, AA3004 et leurs versions modifiées contenant également 1,0 à 2,0 % en poids de fer et éventuellement jusqu'à 1 % en poids de silicium. La couche de cœur est un alliage d'aluminium présentant une limite d'élasticité et/ou une ductilité supérieure(s) à la limite d'élasticité et/ou la ductilité de l'alliage du revêtement de la première surface. L'article stratifié peut être utilisé comme tôle pour des canettes, des extrémités de canettes ou des languettes.
