Title:
MAGNETIC POWDER FOR MANUFACTURING MAGNET, AND MAGNET AND MAGNETIC ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/241736
Kind Code:
A1
Abstract:
The embodiments of the present application provide a magnetic powder for manufacturing a magnet, the magnetic powder comprising a first soft magnetic powder and a second soft magnetic powder, wherein the first soft magnetic powder is a metal crystal soft magnetic material, the second soft magnetic powder comprises at least one of an amorphous soft magnetic material and a nanocrystalline soft magnetic material, and the mass of the first soft magnetic powder accounts for 5%-45% of the sum of the mass of the first soft magnetic powder and the second soft magnetic powder. The magnetic powder can achieve a better molding effect and takes into consideration a higher saturation magnetic flux density and a lower high-frequency loss, etc. The present application further provides a magnet, a magnetic element, and an electronic device.
