Abstract
La présente invention concerne une partie basse de caisson de batteries pour véhicules à moteur électrique ou hybride, réalisée dans une tôle d’alliage d’aluminium ayant une épaisseur comprise entre 2 et 6 mm, dans laquelle ledit alliage d’aluminium comprend, en teneurs pondérales, 2,5 à 4,0 % de Mg, 0,1 à 0,8 % de Mn, 0,4 % au maximum de Si, 0,5 % au maximum de Fe, 0,5 % au maximum de Cu, 0,1 % au maximum de Cr, 0,1 % au maximum de Zn, 0,1 % au maximum de Ti, le reste étant constitué d’aluminium et d’impuretés inévitables jusqu’à 0,05 % chacun et 0,15 % en tout. Un autre objet de l’invention est constitué d’une méthode de réalisation d’une partie basse de caisson de batteries conformément à l’invention, comprenant la coulée dudit alliage d'aluminium pour former une plaque, l’homogénéisation et/ou le réchauffage de ladite plaque, le laminage à chaud et, en option, le laminage à froid de ladite plaque pour obtenir une tôle d’une épaisseur comprise entre 2 mm et 6 mm. La partie basse du caisson de batteries de l’invention est en même temps légère, résistante à la pénétration, suffisamment formable et colmatable, résistante à la corrosion, capable de supporter les variations de température et suffisamment rigide et robuste.
