The present work approaches the increase in ductility and tensile strength through the analysis of the effect of the alloying elements of Al - Si alloys used for high-pressure die casting. The combination of alloying elements providing the best results in terms of ductility and tensile strength were eventually selected to produce a batch of components that were thoroughly tested. The final alloy had a composition of Si 8.21, Fe 0.78, Cu 1.53, Mn 0.64, Mg 0.46, Ni 0.07, Zn 3.37, Pb 0.34, Sn 0.27, Ti 0.18 and Cr 0.04 wt.%. The selected alloy performance was compared to that of the commercial Al - Si9Cu3 and Silafont® 36 alloys.6enginfo:eu-repo/semantics/restrictedAccessjournal article10.3139/146.110877AluminiumCompositionDuctilityHigh pressure die castingCondensed Matter PhysicsPhysical and Theoretical ChemistryMetals and AlloysMaterials Chemistryhttp://www.scopus.com/inward/record.url?scp=84877890567&partnerID=8YFLogxK
