Description of the original method for measuring the coefficient of lateral pressure powders is given. The examples of measurements of lateral pressure coefficients for a number of powders are given. The dependence of the coefficient of lateral pressure metallic powders by compaction pressure and concentration of plasticizer in the material is investigated. It is shown that the coefficient of lateral pressure increases with increasing compaction pressure and growth decreases with increasing degree of plasticizer powder.
