Abstract

Alliage d'aluminium thermo-résistant, contenant de 5 à 10 % en poids de fer, de 0,5 à 3 % en poids de molybdène, de 0,5 à 3 % en poids d'au moins un élément sélectionné parmi le chrome, le zirconium et le vanadium, la quantité totale de fer, molybdène, chrome, zirconium et vanadium étant comprise entre 6 et 16 % en poids, le solde étant essentiellement de l'aluminium. Cet alliage présente une résistance à la traction à 300°C égale ou supérieure à 26 kg/mm2. On produit cet alliage en préparant une poudre d'alliage d'aluminium correspondant à la formulation décrite selon le procédé d'atomisation en fusion, et en solidifiant et moulant le produit à des températures comprises entre 400 et 580°C.
