Abstract
A method of manufacturing soft magnetic material, including smelting magnetic and metallic glass forming compositions, to form a uniform molten master alloy block material, melting the master alloy material into liquid, and exerting a force on the liquid master alloy block material to make it into coarse powder. The coarse powder is screened to separate the working powder, and the working powder is put into an additive manufacturing device, to make the working powder melt, cool and condense into the soft magnetic material. The soft magnetic material is made by a simple process, with low iron loss rate and better electromagnetic shielding feature and other properties, and can improve magnetic permeability and save energy when applied to the electronic products.
