 In this paper the processes of obtaining compacts from heterogeneous powder materials are investigated. The main problem, during the deformation of the powder system, is anisotropy of obtained compact, which results in non-uniform elastic response. Options for solution of problem, based on experimental data, are offered: pressing heterogeneous magnetic systems with high elastic members is recommended for decreasing the velocity of its deformation in order to achieve a uniform density distribution. This approach permits obtaining compact with uniform elastic response, predict and take into account its dimensional accuracy during designing equipment for pressing.
