Abstract

La présente invention concerne des compositions de poudre constituées de particules électriquement isolées d'un matériau magnétique doux d'une poudre de fer ou à base de fer et de 0,1 à 2 o en masse d'un lubrifiant sélectionné dans le groupe constitué des amides d'acide gras possédant de 14 à 22 atomes de carbone. Eventuellement un liant thermoplastique tel qu'un sulfure de polyphénylène peut être inclus dans cette composition. Cette invention concerne aussi un procédé de préparation de ces éléments composites magnétiques doux.
