<abstract xmlns="http://www.w3.org/1999/xhtml">Silumins are one of the most popular group among aluminum casting alloys. They are characterized by good mechanical and casting properties, low density, good electric and thermal conductivity, a low degree of contraction, good corrosion resistance and a relatively low melting temperature.The mechanical properties of hypoeutectic silumins can be improved through chemical modification as well as traditional or technological processing. Modification improves the mechanical properties of alloys through grain refinement. The effect of treatment has been given a lot of information first of all about microstructure and mechanical properties. This study presents the results of treatment of an Al-7%SiMg alloy with composition CuAl10Fe3Mn2 (as a powder) + (Al-7%SiMg + CuAl10Fe3Mn2) (as a powder) + (Al-7%SiMg + CuAl10Fe3Mn2) (in the form of a rod) in three different ranges. The experiments were conducted following a factor design 23 for 3 independent variables. The main addition was aluminum bronze, as well as clear or melted with raw alloy. The influence of the analyzed modifiers on the microstructure and mechanical properties of the processed alloy was presented in graphs. The modification of a hypoeutectic Al-7%SiMg alloy improved the alloy’s properties. The results of the tests indicate that the mechanical properties of the modified alloy are determined by the components introduced to the alloy.</abstract>
