What is a magnetic material

July 17, 2023

1. Magnetic materials:

There are many classification methods for magnetic materials, which can be divided into industrial grade and civilian grade according to their use; According to performance, it can be divided into soft magnetic materials and hard magnetic materials; According to different application ranges, it can be divided into permanent magnetic field materials and Gaussian distributed electromagnets (such as motor rotors).

2. Production process:
1. Selection and treatment of raw materials - Mix various raw materials in a certain proportion and crush them into powder;
2. Ball milling of powder - treating impurities in the powder through a ball mill and distributing them evenly in all corners;
3. Add an appropriate amount of adhesive (such as epoxy resin or phenolic resin) to the powder after ball milling;
4. Add the mixed material into the mold for compression molding (injection molding) - to make the particles in the material come into contact with each other and form a certain shape;
5. Treat the surface of the pressed workpiece and polish it with sandpaper - remove burrs and scratches on the surface of the workpiece and make it smoother and smoother
6. Apply a layer of paint to the surface of the workpiece using spray painting to increase its wear resistance.
