Bonded NdFeB magnet is composed of a special form of NdFeB powder with a plastic carrier material. They have lower energy product than Sintered NdFeB magnet. Very complicated shapes can be produced in Bonded NdFeB magnet with very close dimensions.
Manufacturing Process
Bonded NdFeB magnet is produced by a special form of NdFeB powder blended with a plastic carrier material, die pressed and then heated. Parts made in this way can be of complex shapes and come off the tools with close tolerances, requiring no further finish machining.
Machining
Bonded NdFeB magnet is easily machined. Coolants must be used while machining this material in order to avoid spontaneous combustion of powder. Machining this material is to remove a layer of protective coating, and re-coating for corrosion resistance may be necessary.
Surface treatment
The corrosion resistance of Bonded NdFeB magnet is considered poor, epoxy coating is mostly common used for bonded NdFeB magnet.
Magnetizing
Bonded NdFeB magnet is isotropic and can be magnetized in any direction or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple pole magnetization, depending on complexity of design and production rate requirements.
