FIELD: technological processes; metallurgy.
SUBSTANCE: ferromagnetic powder composition includes soft-magnetic particles on the basis of iron, the surface of which is surrounded with isolating inorganic coating, and lubricating compound from group that includes organosilanes, organotitanates, organoaluminates, organozirconates or their mixtures. Composite material with density of at least 7.45 g/cm3 is prepared by monaxonic pressing of powder composition in mould with at least 800 MPa and by thermal treatment, if necessary.
EFFECT: powder composition makes it possible to facilitate pressing-out and to prepare material with high density.
