FIELD: metallurgy.
SUBSTANCE: method for producing metal powder includes selection of initial raw material and its grinding with control of specific surface of the produced powder, at that specific surface of the initial raw material is determined, and selection of raw material and its grinding is carried out according to condition: 
, where Ss.i. - specific surface area of the initial material (m2/r), Ss.p. - specific surface area of the produced powder (m2/g).
EFFECT: improvement of powder quality expressed in stabilisation of granulometric properties, reduction of morphological diversity of particles, increase of bulk density and improvement of compressibility, reduction of pyrophoricity and sensitivity to friction.
