FIELD: metallurgy.
SUBSTANCE: disclosed composition contains powder A on base of iron preliminary alloyed with molybdenum and containing 6-15 wt % of copper introduced into particles by means of diffusion alloying, powder B on base of iron, preliminary alloyed with molybdenum and containing 4.5-8 wt % of nickel, introduced into particles by means of diffusion alloying, and powder C on base of iron preliminary alloyed with molybdenum. Composition containing powders A,B,C is mixed with graphite, compacted and sintered, producing a sintered component on base of iron containing 0.3-2 wt % of molybdenum, 0.2-2 % of copper and 0.1-4 wt % of nickel.
EFFECT: decreased variation of sizes at sintering, easing of treatment.
