摘要： A compression-molding material, in particular for producing a magnetically soft composite, including a raw powder exhibiting magnetically soft properties, a thermoplastic compound, and a lubricant. The lubricant is especially stearic acid. The compression-molding material is used to produce a magnetically soft composite, whose manufacture includes the method steps of preparation of the compression-molding material, molding of the compression-molding material at a temperature below the melting point of the thermoplastic compound, first thermal treatment of the molded compression-molding material at a temperature below the melting point of the thermoplastic compound, and second thermal treatment of the molded compression-molding material at a temperature above the melting point of the thermoplastic compound. The magnetically soft composite is suitable for manufacturing heat-deformation-resistant, corrosion-resistant, and fuel-resistant, magnetically soft components for high-speed controllers and actuators.

摘要： A soft magnetic material, and a method for manufacturing it, which is suitable, e.g., for use in solenoid valves is described. The individual powder particles of a metallic powdery initial component are equipped superficially at least largely with a high-resistance surface layer and the powder particles are densified into the material. Upon densification of the powdery metallic initial component into the soft magnetic material, the surface layers of the powder particles are additionally at least locally welded to one another. Welding can be achieved using shock densification.
