Wholesale Custom Manufactured Ceramic Magnets from AZ Industries

Ceramic Magnets

Ceramic, or ferrite, magnets are made by the pressing and sintering of a powdered mixture of strontium and iron oxide. They are the most widely used magnets today. Ceramic is inexpensive and corrosion resistant, but cannot withstand impact or flexing as they will chip and crack due to their hard and brittle nature.

No surface treatments are necessary for ferrite magnets. However, a thin film of fine magnet powder on the surface is common and a coating may be used for cleanliness purposes. Common grades of ceramic are 1, 5 and 8 and can be found in the form of discs, rings, blocks, cylinders, and sometimes arcs.

Attributes of Ceramic Magnets

* Economical

* High Hc and Hci compared to Alnico.

* More fragile than other types of magnets, thus manufactured in simple shapes only.

* Require expensive tooling.

* Increased temperature sensitivity.

Ceramic Magnet Applications Include:

* DC Permanent magnet motors

* Separators

* Magnetic Resonance Imaging (MRI) machines

* Magnetos

* DC Brushless Motors

* Speaker Magnets

* Sweeper Bars

* Holding Assemblies

* Humbucker Pickups
