Application of the silumins expands together with nowadays tendency to reduction of design structures mass. Technological and mechanical properties of Al-Si casting alloys depend mainly from structure of eutectic mixture, which is modified in result of introduction of micro alloying elements to liquid alloy, and that is why proper use of knowledge on crystallization to control of crystallization kinetics of produced alloys to optimize obtained structure is a significant factor leading to improvement of quality of the castings. In the paper one depicts use of the ATND method (thermal-voltage-derivative analysis) and regression analysis to assessment of quality of the EN AC-43300 alloy modified with strontium on stage of its preparation, in aspect of obtained mechanical properties (R0,02, R0,2, Rm, A5). Obtained dependencies enable prediction of mechanical properties of the investigated alloy, basing on values of characteristic points from the ATND method.
