Title:
FE-BASED SOFT MAGNETIC ALLOY, METHOD FOR MANUFACTURING SAME, AND MAGNETIC COMPONENT COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/010713
Kind Code:
A1
Abstract:
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 crystal 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. Therefore, the Fe-based soft magnetic alloy can be widely applied to magnetic components of electric and electronic devices for a high-power laser, a high-frequency power supply, a high-speed pulse generator, SMPS, a high-frequency filter, a low-loss high-frequency transformer, a high-speed switch, wireless power transmission, electromagnetic wave shielding, and the like.
