Thank you colleagues for your help! I'm preparing a paper and this topic is very relevant to conclude the ideas. Eliezer

Dear Eliezer Ladeia Gomes ,

Silicon is added to improve the mechanical properties of aluminum. As the content increases, the strength increases at the expense of reducing the ductility. The addition of silicon deforms the crystal lattice of aluminum, which leads to its hardening.

Thank you Dr. Yankov!
