In the present work, hard magnetic Fe-Cr-Co alloys containing 12 and 16 wt. % cobalt were obtained by powder metallurgy method. Molybdenum and silicon were used as alloying additives. Vacuum sintering of this alloys allows us to obtain specimens with relative density 96.5—98.5 %. Comparison of magnetic hysteresis properties of Fe-26 % Cr-16 % Co-2 % Mo- 0,5 % Si and Fe-26 % Cr-12 % Co-3 % Mo-0,5 % Si alloys indicated that alloy with 16 wt. % cobalt content usually has a higher coercivity, while alloy with 12 wt. % cobalt content has a higher residual induction. It was found that magnetic hysteresis properties depend on treatment start temperature and cooling rate in a magnetic field. It is possible under certain settings of thermal treatment to obtain an alloy containing 12 wt. % cobalt magnetic hysteresis properties comparable to standards for alloys with 15-16 wt. cobalt. Using alloys with low cobalt content will reduce the economic cost production of permanent magnets and rotors for hysteresis motors.
