硅钢片： 硅钢是含硅量在3％左右的硅铁合金。硅钢片大量用于中低频变压器和电机铁芯。硅钢的特点是具有常用软磁材料中最高的饱和磁感应强度（2.0T以上），因此作为变压器铁芯使用时可以在很高的工作点工作（如工作磁感值1.5T）。但是，硅钢在常用的软磁材料中铁损也是最大的，为了防止铁芯因损耗太大而发热，它的使用频率不高，一般只能工作在20KHz以下，主要用于工频变压器。 硅钢通常是薄片状的，这是为了减小变压器铁芯的涡流损耗。目前硅钢片主要分热轧和冷轧两大类。热轧硅钢，是把硅钢板坯在850℃以上加热后轧制，然后再进行退火。由于轧制温度高，所轧制出来的硅钢片都是各向同性的，也就是说硅钢片的磁性在各个方向上相同。这种各向同性的硅钢也叫做无取向硅钢。无取向硅钢大量应用在电机中的定子或者转子。因为要制造电机定子和转子，就要在大的硅钢片上冲压出圆形的零件。这时总是希望硅钢片沿圆周方向磁性一致，所以要用无取向硅钢。 为了获得更好的磁性能，后来人们发明了冷轧硅钢片，即在较低温度下轧制，再退火。冷轧取向硅钢片是其中的代表。冷轧取向硅钢片首先对板坯进行冷轧，使得材料内部产生很多结构缺陷。在随后的退火过程中，材料发生结构上的变化（称为再结晶），这种变化会使硅钢片在某个方向上磁性能非常好，也就是说磁性能和方向有关，因此被称为取向硅钢。在最终使用时，让铁芯中的磁力线沿磁性能最好的方向通过，这样便可以最大限度地发挥硅钢片的磁性能潜力。例如，在变压器中，铁芯材料的磁力线是沿一个方向通过的，如果把硅钢片适当裁剪，然后卷绕成铁芯，使得铁芯周长方向恰好是硅钢片磁性能最好的方向，那么铁芯的磁导率就会很高，容易磁化，能量损耗小，最终提高了变压器效率。 我国对硅钢片的编号是：热轧硅钢片D（如D31指含硅3.1％的热轧硅钢）；冷轧硅钢片DT；高磁感取向硅钢片Q和QG。这些材料的磁性能可以从相关的书籍和手册中得到。
20KHz已经是音频的极限频率了！使用硅钢片会产生太多损耗，建议用铁氧体磁芯。
