FIELD: powdery metallurgy.
SUBSTANCE: invention relates to lubricants used in pressing powders. Lubricant for metallurgic powdery composition comprises 10-60 weight % of polyethylene ether and oligomeramide, the balance. The powdery composition comprises lubricant ion-base powder with size of particles 25-350 mcm. Highly strength noncaked articles are made of the proposed powdery composition by pressing at room temperature. Invention provides preparing pressed articles possessing the enhanced strength and low density.
EFFECT: improved and valuable properties of lubricant.
