Abstract
The invention concerns powder compositions consisting of electrically insulated particles of a soft magnetic material of an iron or iron-based powder and 0.1-2% by weight of a lubricant selected from the group consisting of fatty acid amides having 14-22 C atoms. Optionally a thermoplastic binder such as polyphenylene sulphide may be included in the composition. The invention also concerns a method for the preparation of soft magnetic composite components.
