Remarques:
1. Les données de propriétés susmentionnées sont obtenues à la température ambiante.
2. Le coefficient de la température est calculé respectivement entre 20 et 100 ºC pour les degrés avec Hcj <20 kO et entre 20 et 150 ºC pour les degrés avec Hcj> = 20 kOe.
3. La température de travail maximale des aimants dépend de la forme / de la géométrie.
4. Les degrés susmentionnés sont standard et d'autres types peuvent être personnalisés. Le cas échéant, nous produirons des degrés pour des applications spécifiques.
