Bonded NdFeB is an injection magnet manufactured by pressing, so it has excellent magnetic properties, which is only slightly inferior to sintered samarium cobalt. Neodymium-iron-boron bonded magnets can be magnetized without prior magnetic field alignment, and the direction of magnetization can not be limited. However, due to the process factors, the magnetite products still need to be processed by surface coating. In addition, although the temperature resistance and mechanical processing properties of bonded NdFeB magnets are not as good as that of iron oxide injection magnets, the cost of bonding NdFeB magnets is lower than that of iron oxide injection magnets in the opening and magnetizing parts.
The company can provide epoxy resin electrophoresis, acrylic resin electrophoresis, epoxy resin spraying, Teflon spraying, Perrin deposition, vacuum dipping and other coatings and surface treatment processes, so that the products meet the requirements of corrosion resistance, solvent resistance, friction resistance for long-term work in daily and different use environments. Specific coating requirements can be selected and superimposed according to the use environment requirements.
The shape of bonded Nd-Fe-B can be divided into tile (motor magnetic tile), cylinder, ring (ring magnet), abnormal bonded magnet and so on.
The bonded Nd-Fe-B magnetization can be divided into thickness magnetization, radial multipole magnetization (external or internal), radiation charge (radiation ring), plane multipole charge, paired magnetization (tile magnet), oblique charge of radiation ring, etc.
Bonded NdFeB can be widely used in cooling fans, household appliances motors (dehumidifiers, fans, etc.), smart home, magnetic induction and so on.
