Bonded NdFeB magnet

Bonded NdFeB magnet is composed with compression NdFeB magnet, injection NdFeB magnet and flexible NdFeB magnet. Since its birth in the middle of 1980’s, the demand of bonded NdFeB magnet has been dramatically increasing for the industries of automatic control, automobile, 3C products (computer, communication & consumer electronics) and household electric appliance with virtues as follows:
  • Offering new and cost-effective solutions for design and manufacture with availabilities of typical toughness of plastic, diverse and complex geometry, preferred magnetizing pattern, as well as more assembling methods.
  • Extensive choice of property range 1.0—11.5 MGOe.
  • Much better resistance of corrosion than sintered NdFeB magnet.
  • Free-machining by direct molding with net shape and close-tolerance
  • Minimizing figure and weight of application due to its comparatively stronger magnetic property and lower density.
Bonded magnet materials can be made from Ceramic, NdFeB, or SmCo powders which are combined with a variety of plastic binders (Matrix). They can be either Injection Molded or Compression Bonded into complex magnet shapes with finished dimensions. Bonded magnet materials have a moderate resistance to corrosion and a low tolerance to heat because of the binder material. Bonded magnet materials are commonly used in automotive parts because they lend themselves to large production quantities and complex shape can be produced at a low cost.

Injection molded magnets can be formed into complex shapes and be insert molded directly onto other components to produce assembly parts. Compression bonded magnetsoffer higher magnetic output than injection-molded magnets, but are limited to more simple geometries.

Forming methods of Bonded Magnets


Bonded Magnets are formed by either injection molding or compression molding.
Injection molding provides flexible shapes and compression molding provides higher magnetic properties.

Injection Molded:

  • Binder Types / Nylon / PPS / Polyamide.
  • Temperature Range -40c – 180c
  • Very Tight tolerances off tool ( 0.002 -0.003 Typical )
  • Very good mechanical strength

Compression Bonded:

  • Higher Magnetic Strength due to higher magnetic particle density.
  • Epoxy Binder / Resistant to normal industrial solvents and automotive fluids
  • Epoxy Coat after manufacturing to prevent oxidation
  • Temperature Range -40c – 165c
  • “Tight” tolerances off tool
  • Good mechanical strength

Typical Bonded Magnet Applications:

  • Sensors
  • Brushless DC Motors

General Bonded Magnet Applications:

  • Materials are isotropic and can be magnetized in any direction
  • Wide range of existing tool sizes are available in rings, discs and rectangles
  • Exsisting Multipole magnetizing fixtures for quick prototyping
  • Easily machined
  • Existing Multipole rings simplify assembly verse arc sepments

Surface Treatment:

In blending process, NdFeB alloy powder is embedded in epoxy resin or other thermal plastics what are solvent resistant against normal industrial and automotive fluids. Therefore bonded NdFeB magnet is more stable than sintered NdFeB magnet. However if the magnet is working in hot, moist and other corrosive environment, then coating is very necessary. Normally compression NdFeB magnet should have surface treated for protection purpose, meanwhile injection and calender bonded NdFeB magnet are no need to be coated due to high volume fraction of binder.

Compression bonded magnets are available using many isotropic neodymium iron boron material grades as well as crushed & powdered samarium cobalt materials. Combinations of different material grades may also be used to create specific magnetic characteristics. Compression bonded magnets offers higher magnetic strength than injection molded magnets due to their higher magnetic particle density, but are limited to simpler geometries. The epoxy binder used is resistant to normal industrial solvent and automotive fluids. To reduce corrosion of the rare earth magnetic materials, they are further coated with epoxy after shaping. The normal application temperatures range from below -40°C to above 165°C.

Other Properties of Bonded NdFeB Magnets
Hybrid magnets to create different magnetic properties
With different ratio of additives to NdFeB powder, magnetic properties of hybrid NdFeB magnets can be tuned in a wide range. Once the ratio is fixed, magnetic property fluctuation can still be limited in a narrow bank. Hybrid magnets will meet customers’ specified properties.
Characteristics for the initial magnetization of NdFeB bonded magnets
Rapidly quenched NdFeB powder used for bonded magnets is multi grain with grain size of sub-micron. Powder is isotropic in magnetic properties, which results in flat increasing of remanence and intrinsic coercivity with applied field. Magnet can only be magnetized to saturation in high fields.

Injection NdFeB power is blended with a plastic material and injection molded. With High precision of size it can be made of complex shapes and also be bonded with other components. The injection molding magnet can be magnetized in any directions and with multiple poles
Injection NdFeB magnets are with the same application as compression one, but what requires magnets with complex geometry. The character of excellent chip resistance makes handling easier on production assembly line. Injection NdFeB magnet offers more choices including adhesive bonding, additional molding, interference fit and incorporating injection for assembling. Incorporating injection can mold magnetic material into, onto or against other existing components for example shaft, bushes, gears, toothed wheels etc in one process, what brings benefit of saving subsequent assembling cost and enhancing precision of assembly. Tooling cost of making injection bonded NdFeB is also a little more expensive than compaction die.
