Abstract

Procédé pour la fabrication d'une clef comportant des zones à intensité de champ magnétique déterminée. Des évidements sont ménagés de manière connue en soi dans le panneton de la clef, puis de la matière magnétique en poudre est introduite dans les évidements et est ensuite frittée, après quoi la polarité et l'intensité de champ magnétique désirées sont conférées à la matière magnétique frittée. L'invention est applicable à des clefs de serrures magnétiques.
