Publication number: 20220270792Abstract: Provided is a Fe-based soft magnetic alloy. A Fe-based soft magnetic alloy according to an embodiment of the present invention is expressed by the empirical formula FeaBbCcCudNbe, wherein a, b, c, d, and e represent atomic percents (at %) of corresponding elements and satisfy 78.0?a?84.5 and 15.5?b+c+d+e?22.0. Hence, the Fe-based soft magnetic alloy has a high saturated magnetic flux density and high permeability characteristics and thus can be utilized for small and lightweight components, and has low coercive force and low magnetic loss characteristics and thus very easily finds applications in high-performance/high-efficiency components. Furthermore, the Fe-based soft magnetic alloy can minimize the effect of heat treatment conditions in the implementation of uniform grains with a small particle diameter after heat treatment, thereby greatly facilitating the design of process conditions, and thus is very suitable in mass production.Type: ApplicationFiled: July 13, 2020Publication date: August 25, 2022Applicant: AMOGREENTECH CO., LTD.Inventors: Se Joong YOON, Soon Mo HWANG, Yong Sul SONG
