  • Nanocrystalline magnetic conductive sheet for wireless charging and preparation method therefor
    Patent number: 11770022
    Abstract: A nanocrystalline magnetic conductive sheet for wireless charging and a preparation method therefor are provided. The nanocrystalline magnetic conductive sheet includes a composition of Fe(100-x-y-z-?-?-?)MxCuyM?zSi?B?X?, saturation magnetic induction is greater than or equal to 1.25T. The preparation method includes preparing an alloy with a preset composition of into an alloy strip with an initial state of amorphousness by a single roll rapid quenching method, annealing an amorphous alloy strip according to a preset annealing process, to obtain a nanocrystalline strip, performing a magnetic fragmentation process on the nanocrystalline strip, to obtain the nanocrystalline magnetic conductive sheet for wireless charging.
