Common applications
DC and servo motors •
Linear actuators • Magnetic
separators • Speakers
• Microphone
assemblies • Sensors
Please use caution when handling magnetized neodymium magnets, their
exceptional magnetic force may cause them to attract to metal (or to each
other) so strongly that fingers in their path could prove painful.
Machining and tolerances
Neodymium (we like to just call it Neo) is easily ground, although coolants
must be used in the process to avoid spontaneous combustion of powder.
Grinding should be completed before coating or plating is applied to protect
the magnets from corrosion. Standard tolerances for neodymium magnets
are +/-.005” for ground dimensions.

Temperature constraints
The temperature coefficient of neodymium has triggered several grades
to be developed to meet specific operating requirements. Please refer
to our chart of magnetic properties
to compare the characteristics of each grade. Before choosing a neodymium
magnet be sure to consider your application’s maximum operating
temperature.
Magnetization
Neodymium magnets require extremely high magnetizing fields and particular
consideration must be given to this when designing complex assemblies.
Neodymium can be magnetized in any direction as long as it is aligned
properly. In some instances multiple pole magnetization is not possible;
when it is possible, special fixtures are required.
Added value services
Our knowledgeable engineering department is always available to assist
in determining the best grade and size of neodymium magnet for your application.
We also offer coating and plating choices for magnets we custom-machine.
