As an important indicator of quality, each country divides the grade by the iron loss value. The lower the iron loss, the higher the grade and the higher the quality.B. High magnetic induction strength. Under the same magnetic field, the silicon steel sheet with high magnetic sensitivity can be obtained. The volume and weight of the iron core of the motor or transformer made by it are relatively small, which can save silicon steel sheet, copper wire and insulating materials, etc.C. High stacking coefficient. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, which improves the stacking coefficient of the iron core.D. Good punching property. This is more important for manufacturing small and micro motor iron cores.E. The surface has good adhesion and weldability to the insulating film.

电工钢硅钢片：比总损耗(铁损)specific total loss (iron loss)比总损耗是指磁极化强度按正弦变化，其峰值和频率为特定值时，单位质量材料所吸收的总功率，比总损耗用符号 P (Jm/f)表示，单位为 W/kg（或 W/lb）。例：P1.7/50表示在磁极化强度在 1.7T、甘肃临夏当地频率在 50Hz 下测得的单位 kg（或 lb）试样的比总损耗；P1.7/60表示在磁极化强度在 1.7T、甘肃临夏当地频率在 60Hz 下测得的单位 kg（或 lb）试样的比总损耗。3.2 磁极化强度(磁感应强度)magnetic polarization (magnetic induction)磁极化强度是指试样受交变磁场磁化时，特定磁场强度峰值的磁极化强度峰值，其符号为 J(H)，单位为 T(特斯拉)。例：J800表示对应于磁场强度 H 为 800A/m（用峰值表示）下的磁极化强度。3.3 比视在功率 specific apparent power对于设定的磁极化强度和频率值，磁化单位质量的铁芯所消耗的交流电源总功率为比视在功率，其符号为 Ss，单位为 VA/kg。例：Ss1.7/50表示磁极化强度在 1.7T、甘肃临夏当地频率在 50Hz 下测得的单位 kg 试样的比视在功率。3.4 A 计权磁致伸缩速度水平 A-weighted magnetostriction velocity level,LVA 当磁极化强度随时间按正弦规律变化，其峰值为某一标定值，变化频率为某一标定频率时，单位长度电工钢片（带）沿磁化方向上发生磁致伸缩所引起的表面振动声压水平为 A 计权磁致伸缩速度水平。
