具有｛１１０｝＜００１＞位向３％Ｓｉ－Ｆｅ带适用于频率从１０２～１０５Ｈｚ的中、高频范围电磁装置铁芯材料。在这一范围内，要求铁损低、磁导率高。最近开发了高取向度材料，把励磁频率和磁通密度作为函数，研究影响铁损的物理参数。铁损和励磁条件之间的关系分成四个区域，这种材料适用于变压器和电器，特别适用于中频领域内高磁通密度装置（最大励磁磁通密度＞１Ｔ，１０２～１０３Ｈｚ），如航空电器。
With {110} <001> 3% Si-Fe band for the frequency from 102 ~ 105Hz medium and high frequency range of electromagnetic device core material. In this range, requiring low iron loss, high permeability. Recently, a highly oriented material has been developed that uses excitation frequency and flux density as a function to study the physical parameters that affect iron loss. The relationship between iron loss and excitation conditions is divided into four areas. This material is suitable for use in transformers and appliances. It is particularly suitable for high flux density devices (maximum field flux density> 1T, 102 ~ 103Hz) Electrical appliances.
