Abstract: This work presents the results of influence the chemical composition on the quality of castings, obtained using the wax models. After molding the wax models and melting the wax in a dryer, the mold cavity was filled with liquid metal. Four series of castings with the following chemical composition were cast: first series (Cu=90.5%; Sn=6.5%; Zn=3.0%), second series (Cu=83.7%; Sn=7.0%; Zn=9.3%), third series (Cu=90.2%; Sn=1.5%; Zn=3.0%; Pb=3.3%; Fe=2.0%) and fourth series (Cu=85.0%; Sn=5.0%; Zn=5.0%; Pb=5.0%). Based on the obtained results, a lack of filling was observed on a candlestick from the fourth series of castings. The quality of other castings is satisfactory, which refers to the external look. Faults in the form of voids are present, but minimal surface finishing allows obtaining the castings with relatively smooth surfaces.
