Title
(EN) ALUMINIUM ALLOYS, COATED ALUMINIUM ALLOY PRODUCT, CLAD ALUMINIUM ALLOY PRODUCT WITH HIGH CORROSION RESISTANCE
(FR) ALLIAGES D'ALUMINIUM ET ALLIAGES D'ALUMINIUM REVÊTUS PRÉSENTANT UNE HAUTE RÉSISTANCE À LA CORROSION ET LEURS PROCÉDÉS DE FABRICATION
Abstract
(EN) Provided herein are new aluminum alloys comprising Ca, Mg and/or Zn and new coated aluminum alloys comprising surface layers (e.g., coatings) comprising Ca, Mn, Zn, and/or Ni that can be used in aluminum alloy products, such as clad layers. Also provided are methods of making these aluminum alloys, coated aluminum alloys, and clad layers, as well as clad products. These alloys, coated alloys, clad layers, and products possess a combination of strength and other key attributes, such as corrosion resistance, formability, and applicability of paint line pretreatments. The materials can be used in a variety of applications, including automotive, transportation, and electronics applications.
(FR) L'invention concerne de nouveaux alliages d'aluminium comprenant du Ca, du Mg et/ou du Zn et de nouveaux alliages d'aluminium revêtus comprenant des couches de surface (par exemple des revêtements) comprenant du Ca, du Mn, du Zn et/ou du Ni, pouvant être utilisés dans des produits en alliage d'aluminium, tels que des couches de placage. L'invention concerne également des procédés de fabrication de ces alliages d'aluminium, de ces alliages d'aluminium revêtus et de ces couches de placage, ainsi que des produits plaqués. Ces alliages, alliages revêtus, couches de placage et produits plaqués présentent à la fois une résistance mécanique et d'autres attributs clés, tels qu'une résistance à la corrosion, une formabilité et une applicabilité de prétraitements en chaîne de peinture. Ces matériaux peuvent être utilisés dans diverses applications, notamment dans l'automobile, les transports et les applications électroniques.
