随着大面积集成固体电路的飞速发展,电子元件已大大微型化,因此,愈来愈要求磁性材料高磁感、高导磁、低铁损,以期缩小磁性器件的体积和重量,并提高功率。为此,近年来我国精密合金有关生产厂、科研单位和高等院校对Si—Fe、Fe—Ni和Fe—Co系软磁合金进行了大量的工作,取得了可喜的进展。
With the rapid development of large-scale integrated solid-state circuits, the electronic components have been greatly miniaturized, therefore, the magnetic materials are increasingly required to have high magnetic induction, high permeability and low iron loss in order to reduce the size and weight of magnetic devices and improve the power . To this end, in recent years, China’s precision alloy-related manufacturing plants, research institutes and institutions of higher learning on the Si-Fe, Fe-Ni and Fe-Co soft magnetic alloy has done a lot of work and made gratifying progress.
