The composite magnetic powder is processed from the magnetic material NdFeB magnetic powder
NdFeB magnetic powder is a kind of special magnetic powder in magnetic materials. Jinzeli special alloys have learned that the production of composite magnetic powder is to take advantage of the anisotropic properties of NdFeB magnetic powder and to use it with lower-priced ferrites. Made of powder mix. The amount of ferrite powder added is controlled at about 30%, and composite magnetic powders with the same properties as the magnetic powder can be obtained, and the price is far lower than that of the same magnetic powder. The composite magnetic powder guarantees the magnetic properties of the material and greatly reduces the cost, so we can use this composite magnetic powder to replace the same type of NdFeB magnetic powder.
Composite magnetic powder is anisotropic material, characterized in that the magnetic powder must be formed in the orientation magnetic field, and is magnetized in the molding process. The larger the orientation magnetic field, the higher the orientation degree, the higher the magnetic properties of the magnet, and the ideal state is to achieve saturation orientation. .
At present, the composite magnetic powder is used for compression molding, and it must first solve the problem of the orientation magnetic field. Many domestic and foreign enterprises and scientific research institutions are developing molding presses with oriented magnetic fields. If molding equipment is solved, the use of composite magnetic powders to make molded magnets will rapidly develop.
