Bonded NdFeB magnets, are composed of a |
special form of NdFeB powder with a plastic carrier |
material. They have lower energy product than |
Sintered NdFeB magnets. Very complicate shapes |
can be produced in Bonded NdFeB magnets with |
very close dimensions. |
Manufacturing Process |
Bonded NdFeB magnets 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 tool with close tolerances, requiring |
no further finish machining. |
Machining |
Bonded NdFeB magnets is easily machined. |
Coolants must be used while machining this material |
in order to avoid spontaneous combustion of |
powder. Machining this material removes a layer of |
protective coating, and re-coating for corrosion |
resistance may be necessary. |
Surface treatments |
The corrosion resistance of Bonded NdFeB magnets |
is considered poor, epoxy coating is mostly common |
used for bonded NdFeB magnets. |
Magnetizing |
Bonded NdFeB materials are 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. |
