Results of mechanical properties of high-pressure die-casting AZ91 magnesium alloy are presented. Performed examinations allowed to determine influence of plunger velocity in the first and second stage and intensification pressure on the ultimate tensile strength (UTS), yield strength (YS), elongation (A5 and Agt), Brinell hardness (HB) and impact strength (IS) of samples cast on 320 tone cold chamber machine. Obtained results revealed the highest properties at median used parameters and also the most powerful effect of plunger velocity in the first stage. The maximum values of mechanical properties obtained from the performed experiments were: UTS 250 MPa, YS 160 MPa, A5 7%, 70 HB, IS 7 J.
