This paper presents technological solution which makes possible to obtain the composite materials with the controlled ferromagnetic and mechanical properties. The composite materials were made by binding the Fe73,5Cu1Nb3Si13,5B9 (FINEMET) alloy with high density pressureless polyethylene (PEHD). The ferromagnetic powders of Fe73,5Cu1Nb3Si13,5B9 alloy were made by high-energy milling of tapes after their thermal nanocrystallization. Manufacturing technology of the composite materials depends on connecting the fabricated components by one-sided uniaxial pressing.
