In this study a general scheme expressing the factors which affect a workability of powder materials is presented. It was found from laboratory experiments that workability of powder metal materials is limited by their density. Aluminium based materials with additions of Cu, Ni and Sn were used in the experiments. Workability determined in compression tests depends strongly on a sintered density, independently of the chemical composition of material. A linear dependence between workability and sintered density was found. The results are related to relatively high density values, taken from the range of 0.85-0. 96 of theoretical density.
