Claims (4)

1. Procédé de fabrication de produits laminés en aluminium qui contiennent du fer comme élément d'alliage principal et qui, à leur épaisseur finale, après un revenu à au moins 250°C, présentent une grosseur de grain inférieure à 10 microns, caractérisé en ce que l'on coule un alliage constitué de 0,8 à 1,5% de fer, respectivement, jusquà 0,5% de silicium et de manganèse, étant précisé que la somme du silicium et du manganèse se situe entre 0,2 et 0,8%, .et d'autres constituants allant jusqu'à respectivement 0,3%, au total jusqu'à 0,8%, et, pour le reste, d'aluminium, avec une vitesse de solidification allant de 2,5 à 25 cm/min; en ce qu'après laminage à chaud, on le ramène à des températures inférieures à 120°C avec une vitesse de refroidissement d'au moins 0,5 K/s; et ce qu'ensuite on le lamine à froid jusqu'à une diminution d'épaisseur d'au moins 75% sans revenu intermédiaire; et en ce que la température de revenu, à l'épaisseurfinale, ne dépasse pas 380°C.
2. Procédé selon la revendication 1, caractérisé en ce que l'alliage d'aluminium employé contient plus de 1,1% de fer et plus de 0,25% de manganèse.
3. Procédé selon la revendication 1 ou 2, caractérisé en ce que le rapport en poids de la proportion de fer à la proportion de manganèse se situe entre 2,5 et 4,5.
4. Procédé selon au moins l'une des revendications 1 à 3, caractérisé en ce que l'alliage d'aluminium employé contient, en dehors du Fe, du Si et du Mn, au maximum respectivement 0,1% de tout autre constituant.
