The effects of the die temperature and pressure applied to the liquid melt on structural changes and mechanical properties of wrought 1960 alloy (in Russia) obtained by squeeze casting were investigated. It was shown that a dendrite structure containing primary intermetallic phase particles is formed in the alloy during squeeze casting at the die temperatures 200 and 400 oC and applied pressures 90 and 350 MPa. At that the cast billets without any macroscopic defects can be obtained only at the die temperature of 400 oC. At this temperature, the volume fraction of inter-metallic phase particles was 9%, and the size of dendrite crystals are increased from ~500 to ~600 µm with increasing of the applied pressure. The strength properties of alloy are raised with increasing of die temperatures and applied pressure. At this the ductility of alloy was the less 1 %.
