Measuring results on shock compression of porous aluminum with initial density of ρ00 = 0.6 g/cm3 up to pressures of 170 GPa are presented under shock wave velocity measurement scale of 40 mm. High underground explosion was used as a shock wave source. Obtained results were described in shock wave velocity (D) — particle velocity (u) coordinates by linear dependence of D = 0.647 + 1.26 u at 4.6 ⩽ u ⩽ 14.8 km/s.
