Hitachi Powdered Metals and Denso developed new magnetic parts which consists of a high performance powder base soft magnetic core and a composite armature, and have been installed as magnetic parts in injectors for common rail systems meeting the EURO V regulation. The new powder base soft magnetic core for the stator, had achieved both high magnetic properties and outstanding machinability as a result of various improvements of the insulation property of the iron powder itself, optimization of the resin content and addition method, and optimization of the heat treatment method. On the other hand, the composite armature had achieved combined properties of good wear resistance, wrought steel, and excellent magnetic properties, sintered magnetic core, in a single device by using the sinter diffusion bonding method. These properties are more excellent than conventional parts. As a result, the performance of the injector has improved drastically.
