Abstract

L'invention vise à proposer un alliage d'aluminium de la série 7000 Al-Zn-Mg-Cu qui présente une ductilité élevée pour sa résistance élevée. Pour atteindre ce but, un alliage d'aluminium de la série 7000 Al-Zn-Mg-Cu, ayant une structure exempte d'inclusions, est obtenu par réduction de la teneur en oxygène d'un alliage d'Al obtenu par solidification rapide d'un alliage d'aluminium de la série 7000 Al-Zn-Mg-Cu fondu en une préforme avec un gaz inerte, de préférence par formage par pulvérisation. L'alliage d'aluminium de l'invention a une résistance à la traction de 600MPa ou au-dessus en tant que l'une des caractéristiques mécaniques à température ordinaire et présente un allongement de 15% ou plus lorsque la résistance à la traction est de 600 MPa ou plus mais au-dessous de 800 MPa et un allongement de 10% ou plus lorsque la résistance à l'attraction est de 800MPa ou plus, présentant une excellente aptitude au façonnage à froid telle que l'aptitude au laminage.
