Abstract
High ductility Al-Mg alloys often contain some Mn and Si, however the effects of these minor alloying elements on various properties of alloys have not been fully understood. In this study the castability and mechanical properties of Al-5%Mg alloy were investigated according to the addition of Mn and Si. The fluidity of the alloys was generally increased by increasing Si or Mn contents. The feedability was also increased by increasing Si content, but it was rather decreased by increasing Mn content. Both the tensile strength and the ductility appeared to be deteriorated by Si addition, while they were found to be improved by Mn addition.
