The article presents the results of plastic shaping tests of AZ61 and WE43 alloys. There were both classic extrusion tests as well as extrusion tests of KOBO method. An assessment was made of the influence of extrusion process parameters on the mechanical properties and the structure of the alloys. On the basis of achieved results of mechanical properties for alloys AZ31 and WE43 the susceptibility of those alloys to plastic shaping was determined. Quantitative tests of structure assessment in case of alloys AZ61 and WE43 after extrusion with the use of KOBO method were conducted with the use of METILO program. It has been shown that extrusion AZ61,WE43 alloys method KOBO leads to considerable fragmentation of grains.
