National Magnetics Group, Inc. National Magnetics Group, Inc.

We have an extensive number of tools covering a wide variety of dimensions – call us with your requirements. Close tolerances can be held by grinding. Typical shapes available (for all materials):

• Rings (can be designed with slots, notches, counter bores, etc.)
• Discs
• Rectangles/Squares (can be designed with inner diameters)
• Custom Shapes

Key features of ceramic magnets:

• Resistant to demagnetization (high coercive force)
• Non-conductive
• Can be magnetized before or after assembly
• Chemically inert
• Made from non-strategic raw materials
• Can be magnetized (ie. axial, diametrical, radial or multi-pole) in any direction

Common applications:

• Holding (chip collectors, latches, seals, toys, etc.)
• Electrical-Mechanical (torque couplings for water meters, reed or hall switch actuators, relays, rotors, frictionless bearings for watt-hour meters, instruments, etc.)
• Electronic and Polarizing (magnetic focusing or deflection,
