Abstract
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.
