Abstract

The experimental results of the combination extrusion process for ENAW-1050A aluminium alloy are presented. Depending on the punch and die sizes used, the tests were performed for three different values of relative strain in backward direction, 2, and a constant strain in forward direction, 1. The test aimed at determining the effect of friction on maximum values of punch forces. Non-lubricated and lubricated (zinc stearate) extrusion processes were used.
