Injection Molded Epoxy Coated Bonded Neodymium Magnets
About Compression Bonded Magnets
Advantages Of Compression Bonded Magnets
1: Higher magnetic strength than injection molded magnet.
2: High corrosion resistance (Epoxy coating, parylene coating) and temperature resistance, the salt spray teasting >72 hours
3: Magnetizing with complex patterns (Multi-poles on OD, ID, end face (axial), radial, helical magnetization......)
4: Higher magnetic property (Br: 3500-8000G, BHmax: 3-12MGOe, Hcj: 4000-17000 Oe
5: Complicated shape
