This article describes the results of studies on the extrusion of hard-to-deformable aluminum alloys using a controlled extrusion barrel temperature method. The range of extrudable deformation as the limit deformation under the specified technological conditions was determined. The measures to prevent the crack of the extruded material when the exit velocity was maximum were also presented. The article also listed the initial test die used to calculate the extrudability of metal The physical model of 99.99% lead and the extrudability of different plasticity aluminum alloys are also listed. A relatively fast extrusion test using a given metal and a specific test die is introduced and the test results are analyzed.
