铁硅铝磁粉芯（Kool Mu）是由85%Fe，9%Si，6%Al的合金粉末生产出来的一种金属软磁材料，其最先是由二十世纪三十年代日本人发明的，因其发明地点在日本仙台，故又称为Sendust合金，而美磁公司（Magnetics）称其为Kool Mu，由于该铁芯是一种低损耗和相对高的饱和磁感应强度（10500高斯）的磁性材料，所以非常适用于功率因数校正电路（PFC电感器），脉冲回扫变压器和储能滤波电感器。该软磁材料磁致伸缩接近零，也特别适用于消除在线噪音的滤波器。铁硅铝磁芯在制造过程中不用有机粘合剂，因此没有热老化的问题，可长期使用在200℃的工作范围。目前可生产磁导率从26μ~125μ、及各种形状的产品（有环形、U型、E型、块状型）是一种性价比优异的粉末磁芯。
