Abstract: The present disclosure provides a magnetic composite material composition, a magnetic core for an inductor and a manufacturing method therefor. It includes a magnetically soft alloy, a thermosetting resin, a curing agent, and an organic solvent. The organic solvent contains at least two types of volatile solvents, and a difference between boiling points of the volatile solvents ranges from 100 to 170° C. The magnetically soft alloy and the thermosetting resin may be cured and formed under the action of the curing agent. The magnetic composite material of the above composition has good high-temperature resistance. Different types of the volatile solvents may be successively volatilized rather than rapidly volatilized at one time as the curing reaction undergoes. Therefore, a large amount of pores can be prevented from being produced on the surface and internal of the magnetic composite material composition, thereby enhancing the compactness and relative permeability.

Abstract: The present application provides a soft magnetic alloy sheet, a preparation method therefor and a use thereof. The preparation method comprises the following steps: (1) mixing thermosetting resin, thermoplastic resin, a solvent, a curing agent, and soft magnetic alloy powder having insulating coating to obtain casting slurry; and (2) carrying out degassing and casting-drying treatment on the casting slurry in step (1) in sequence to obtain the soft magnetic alloy sheet.
