Early-developed nanocrystalline Fe_(73.5)Cu_(1.0)Nb_3Si_(13.5)B_9 and Fe_(73.1)Cu_(1.2)Nb_(3.2)Si_(12.5)B_(10) alloyshave shown superior synthetical soft magnetic properties; however, they contain the ex-pensive element Nb and their amorphous ribbons are brittler. In order to make cheaperFe-based nanocrystalline alloys, the authors have made a nanocrystalline Fe_(69.4)Cu_(0.6)Cr_(3.2)V_(0.8)-Si_(14)B_(12) alloy by replacing Nb by much cheaper Cr and V.
