FIELD: metallurgy.
SUBSTANCE: powder composition contains iron powder or powder on the basis of iron and 0.05-0.4 wt % of lubricant. Lubricant corresponds at least one substance from group: nondrying oil or liquid with melting temperature lower than 25°C and viscosity, calculated according to the formula 10 log η = k/T + C, where η - viscosity; k - angular coefficient preferably more than 800, T - temperature according to Kelvin scale, C - constant. Viscosity is more 15 mPa·s at 40°C.
EFFECT: high density and reduction of ejection force pressing from matrix.
