This paper discusses the process of direct and indirect extrusion of rods, profiles, tubes, etc. for a series of MgAlZn magnesium alloys, which are suitable for heat treatment to obtain the highest strength. These products have been manufactured at the Institute of Non-Ferrous Metals, Light Metals Division (IMN OML) in the form of billets with a 100 mm diameter. The extrusion process was performed in the temperature range between 320°C and 430°C and at the ram speed of 0.5 to 5.0 mm/s. The impact of heat treatment on the mechanical properties of magnesium alloys was also the subject of this study. The tested magnesium alloys had higher mechanical properties for temper T5 than for temper T6. In conclusion, reference is made to the possibilities of practical application of the results obtained.
