Description

technical field

[0001] The invention belongs to the technical field of magnetic material preparation, and in particular relates to an insulating binder for preparing metal soft magnetic powder cores and a method for using the same. Background technique

[0002] Metal soft magnetic composite material (also known as magnetic powder core) is a kind of soft magnetic material made of metal soft magnetic powder by powder metallurgy process. The rapid development of information technology and electromechanical industry requires high frequency, miniaturization, intelligence and low loss of magnetic devices. Compared with the commonly used silicon steel sheet and soft ferrite, the metal soft magnetic powder core has great advantages in these aspects. Magnetic powder core has many advantages, such as high magnetic flux density, high magnetic permeability and low cost, so it is widely used, but in practical applications, the resistivity of metal magnetic powder core is too low, result...
