Magnetische Materialien sind grundlegende funktionale Materialien der Elektronik-Industrie. Genauso wichtig, Teile von magnetischen Werkstoffen, harten Ferrit Materialien spielen eine Heavyrole in der Elektronik-Industrie, elektronische Informationsindustrie, Automobilindustrie, Motorrad-Industrie etc. inzwischen, sind sie auch in ärztliche Behandlung, Bergbau und Hüttenwesen, Industrieautomation, Öl Energieindustrie und zivilen verbreitet. Ferrit-Magnet Ferrit-Magneten, verklebte Ferrit-Magnet, Barium-Ferrit-Magnet, harten Ferrit-Magnet, gesintertem Ferrit-Magnet, verklebte Ferrit Injektion magnet
Unsere Hauptprodukte sind: harte Ferrit Bogen oder Segment, Ringmagnete, rechteckigen Magnete, Ferrit macht etc.. Die haben folgende Vorteile: hohe Zwangsmaßnahmen, hohen elektrischen Widerstand, Langzeitstabilität und günstigen Preis. Unterdessen können wir neue Werkzeuge entsprechend der Kundennachfrage herstellen. Ferrit-Magnet, Ferrit-Magneten
