Abstract
Free cutting alloys of Al-Cu (AA2011 and AA2111B) in T6 temper and Al-Mg-Si system (AA6023 and AA6262) in tempers T6 and T8 were subjected to Charpy U - notch impact testing at the temperatures ranging from 20oC to 350oC. The microstructure of the materials was characterized by light metallography, fracture surfaces were observed using scanning electron microscope (SEM).
