Two Al-Mg alloys were subjected to extrusion for fabricating ferrules and the mechanical behavior of the extruded ferrules was investigated. To estimate the proper extrusion conditions, the power dissipation efficiency and plastic instability of the Al-Mg alloys were assessed by the construction of deformation processing maps. The Al-1.5Mg alloy ferrule had a higher work hardening capacity than the Al-0.9Mg alloy ferrule, which resulted in a higher load bearing capacity in the former during the extension test of wire rope slings.
