Custom Ceramic Magnets and Magnetic Assemblies

Ceramic magnets, or ferrite magnets, are low cost, lightweight, moderate energy permanent magnets capable of withstanding operating temperatures of up to 480°F. They are highly corrosion resistant and work well in high volume applications. These qualities make them a popular choice in manufacturing and consumer applications such as speaker magnets, DC motors, reed switches, sweepers, MRIs, and automotive sensors.

The most popular grades of ceramic magnet are 5 and 8. These are anisotropic grades, which are considered the most powerful. Anisotropic magnets experience magnetization exclusively in the direction formed during the pressing operation, resulting in a magnet with an overall magnetic flux output. Ceramic magnets can be made in many shapes and sizes, can be ground to intricate and accurate shapes, and can even be designed to be small enough to be used in micro applications.
