The paper presents compression test results of self-made open-cell aluminium which was produced by the investment casting method. Two groups of samples were studied: prototype samples containing some structural imperfections (apparent density 0.485 g/cm3 ) and regular samples without visible mistakes (apparent density 0.312 g/cm3 ). Performed experimental research covered quasi-static compression tests with one hysteresis loop. Based on experimental results, new measures to help material characterisation were proposed: instant and average loop secant gradients (E**inst.sec and E**av.inst.sec) and average linear loop gradient (E**av.lin).
