Aleaciones de aluminio multicomponente con propiedades mejoradas de agrietamiento en caliente y porosidad reducida

The invention relates to new multicomponent aluminium alloys, with certain proportions of zinc, copper, magnesium and silicon; these alloys have fine microstructures, which allow their processability by means of different manufacturing techniques, including technologies where the rapid solidification of the process presents hot cracking problems and processes where porosity is generated. The invention also relates to the use of the alloys for the manufacture of articles by means of near net shape manufacturing techniques, and to articles comprising said alloys.
