Matériaux magnétiques sont des matériaux fonctionnels fondamentaux de l’industrie électronique. Aussi importantes pièces de matériaux magnétiques, ferrites durs jouer un heavyrole dans l’industrie électronique, industrie de l’information électronique, industrie automobile, industrie etc. de moto dans le même temps, ils sont aussi largement utilisés dans les traitements médicaux, mines et métallurgie, automatisation industrielle, industrie de l’énergie pétrolière et l’industrie civile. aimant en ferrite, aimants ferrite, aimant en ferrite servile, aimant ferrite de baryum, aimant en ferrite dur, aimant en ferrite fritté, aimant en injection ferrite sous douane
Nos produits principaux comprennent : ferrite dur arc ou segment, aimants d’anneau, des aimants rectangulaires, puissance de ferrite etc.. Qui présentent les avantages suivants : force coercitive élevée, haute résistance électrique, stabilité de longue date et prix économique. En attendant, nous pouvons fabriquer des nouveaux outils selon la demande des clients. aimant en ferrite, aimants ferrite
