Description

technical field [0001] The invention belongs to the field of metal soft magnetic material manufacturing, and in particular relates to a composite FeNi material with a magnetic permeability of 100 and a manufacturing method thereof. Background technique [0002] At present, with the continuous upgrading of the circuit, the electronic components in the circuit require higher current, and require magnetic components with high magnetic permeability, high saturation magnetic flux density, and small magnetic permeability drop after the additional current bias field. Metal magnets have a higher saturation magnetic flux density than ferrite magnets, and metal materials are used as the main material of magnets as new objects of use. However, with the development of miniaturization and thinning of electronic products, electronic components are required to be miniaturized and thinner as well. However, with the miniaturization of magnets, materials with high magnetic permeability among...
