For that purpose, Al-4% Cu-0, 5% Mg alloys were tested with silver content in proportions of 1.5%, 2.5% and 3.5%. Precipitation hardening was carried out by homogenization heat treatment of solid solutions. The microstructure analysis was carried out using optical microscope and SEM, Vickers hardness tests was also performed, tests of tensile strength and electrical conductivity, which were compared with the alloy A356-T6. The results of this research show that the increase of silver in the alloy increased tensile strength and decreases the resistivity. By SEM and EDS analysis of the phase ɵ (CuAl2), Al6 (Cu, Fe) and Al7Cu2Fe was observed. 2014 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49631663022 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.186 Vol.81
