Aluminum powders with contents of 2%-14% were added into the formulation when the temperature of emulsion explosive is about 70 ℃. Electrical measurement was used to get the detonation velocity of emulsion explosive containing aluminum, and the underwater tests were used to obtain the shock wave energy and bubble energy of explosive. At the same time the explosion heat was calculated by GAS triangles. The effects of aluminum powder contents on performance of emulsion explosive were analyzed. The results show that detonation velocity of emulsion explosive containing aluminum decreases with the increasing of aluminum powder contents, but explosion heat, shock wave energy and bubble energy increase with the increasing of aluminum powder contents.
