Main problems arising in installation of novel processes of production of permanent magnets based on the Fe – Cr – Co and Sm – Co systems are presented. The technological possibilities of production of permanent magnets from an alloy of the Fe – Cr – Co system by methods of MIM technology and powder metallurgy are described. Methods of MIM-technology with the use of domestic granulate are used to fabricate permanent magnets based on alloy 25Kh15KA (Fe – Co – Cr system) with residual induction Br = 1.12 T, maximum energy product (BH)max = 23.0 kJ/m3 and coercivity HcB = 39.7 kA/m.
