Purpose: The purpose of the paper is to present the material and technological solution which makes it possible obtaining soft and hard magnetic composite materials: nanocrystalline material – polymer. Design/methodology/approach: For fabrication of composite materials the following powders were used: soft magnetic materials (Fe73.5Cu1Nb3Si13.5B9) and hard magnetic material (Nd14.8Fe76Co4.95B4.25) with nanocrystalline structure. Composite materials were bonded by the use of following binder (2.5 % wt.): thermoplastic polyethylene and thermosetting epoxy resin, respectively. Advanced composite materials were compacted by the one-sided uniaxial pressing. Findings: The complex relationships among the manufacturing technology of these materials, their microstructure, as well as their magnetic and mechanical properties were evaluated. The manufacturing of composite materials greatly expand the applicable possibilities of nanocrystalline powders of magnetically hard and soft materials however further examination to obtain improved properties of magnetic composite materials and investigations of constructions of new machines and devices with these materials elements are still needed. Practical implications: Results of investigations of properties and the structure of magnetic composites allow to widen their application possibilities. In manufactured composite materials there is found a good correlation between mechanical and magnetic properties what is very important taking into account the possibility of their application because these composite materials can be used both in stationary devices and in portable ones which are more commonly used. Originality/value: This is an example of simple technology allowing to expand the possibilities of magnetic hard and soft materials.
