It is found that CP aluminium exhibits sticking whereas Al-Zn alloys do not exhibit sticking at elevated temperatures. Hot working of Al-Zn alloy is easier than that of CP aluminium at 773 K. As zinc content increases up to 10 wt% the friction factor decreases up to 0.02. © Indian Academy of Sciences.Compression testingFrictionHot workingThermal effectsZinc alloysFriction factorSlidingStickingAluminum alloys
