anisotropic ferrite magnet production process

About Ferrite Magnet

Ceramic magnets are used for many consumer & commercial applications such as craft projects, refrigerator magnets, badge holders, latches, display boards, motors, lifting magnets, science projects, toys, games, POP displays, advertising giveaways & much more. 

Attributes of Ceramic Ferrite Magnet

High intrinsic coercive force

Least expensive material compared to alnico and rare earth magnets

Limited to simple shapes due to manufacturing process

Lower service temperature than alnico, greater than rare earth

Finishing requires diamond cutting or grinding wheel

Lower energy product than alnico and rare earth magnets

Most common grades of ceramic are Y10T(C1),Y30(C5) and Y33(C8)

How to Make Ceramic Magnet

Precautions for use

1. Consider the decrease of intrinsic coercivity at low temperature to avoid demagnetization.

2. A ferrite magnet is especially hard and fragile. When it is exposed to vibration or impacts, design the structure properly.

3. When thermal shock is applied to a magnet, magnet breakage may occur. Never expose a magnet to thermal shock such as a rapid heating or cooling speed.

4. If magnets rub against each other during transportation, magnet powder may be seen on the surface.
