Abstract
The invention discloses iron-based soft magnetic composite powder which is characterized in that the iron-based soft magnetic composite powder comprises iron-based soft magnetic powder and aluminum powder; the iron-based soft magnetic powder is loaded on the aluminum powder; the composite material can still have high magnetic permeability under the condition that the adding amount of the iron-based soft magnetic powder is reduced, so that the weight of the whole composite material is reduced, and the application range of the composite material is widened.
Description
technical field [0001] The application relates to an iron-based soft magnetic composite powder and a preparation method thereof, belonging to the field of alloys. Background technique [0002] Soft magnetic materials have appeared as early as the nineteenth century. Soft magnetic materials are easy to magnetize and demagnetize, so they have the characteristics of high magnetic permeability and low coercive force, and they play a very important role in various electronic devices. Iron-based soft magnetic powder is a relatively common soft magnetic powder, which has the characteristics of good saturation magnetic induction, magnetic permeability, low power loss, etc., and is widely used in communication, aerospace, radar and other fields. Important materials for key components such as sensors. However, for general iron-based soft magnetic powders, their own characteristics cannot fully meet the applications requiring high saturation magnetic induction. In addition, in order ...
