The work includes structure characteristics as well as mechanical, corrosive and biocompatible properties of Mg-Y and Mg-Li alloys with 0.2%Ca, 1%Ca and 1%Zn after die casting. The structure showed a significant effect of the amount of alloying additives on the morphology of the phases occurring mainly at the grain boundaries. The composition of alloy also affects the possibility of fragmentation of the structure. The strength properties were highest in alloys with 1%Zn and 0.2%Ca. Analysis of the biodegradation results carried out in Ringer's solution showed the slowest dissolving alloys with low Ca content. The higher Ca content influenced the increase the share of Mg2Ca phase in the alloy, which is the catalyst for the corrosion processes along the grain boundaries. Examination of Mg alloys carried out under sterile conditions at 37°C in Alpha-MEM solution after 144h showed a high biocompatibility of Mg alloys containing Li, Ca and Zn additions.
