Isotropic ferrite magnets
Anisotropic ferrite magnets
Ceramic ring magnets, also known as Ferrite Ring Magnets, come in a wide range of sizes. They are often used in loudspeakers and in resonance imaging and torque drives. Other applications for this permanent magnet include holding, door closures, joinery, and light fixtures. Ceramic Rings are similar to Ceramic Discs but with a hole in the middle, which makes them a versatile magnet option. One popular application is the fishing game, tied on a piece of string, or to pick up pins and needles. Ferrite magnets have less magnetic strength (due to the hole) but their inexpensive pricing makes them a customer favorite.
Ceramic magnets are manufactured using powder technology techniques, meaning they can easily be magnetized or attracted to a magnet. Ferrites can be divided into two families based on their resistance to being demagnetized (magnetic coercivity). Strong Ring Sintered Ferrite Speaker Magnet Y25 D80X40X10mm
Hard Ferrite ceramic magnets were developed in the 60’s and today comprise 75% of world magnetic consumption. Despite their relatively low magnetic values, they are the most popular magnet on the market due to ready availability and relatively low cost.
The raw material from which ferrite magnets are produced is Strontium Ferrite powder (mainly ScO.6Fe203) which is formed in a press while subjected to an electric field. This process allows the direction of the magnetic field to be determined during the production of the magnet. Ring Shape Audio Loudspeaker Ferrite Magnet
Ceramic Ring Features
Ceramic rings offer economical magnet power for price sensitive applications when you need low cost, good holding strength, and great value.
Ceramic ring magnets are a dark charcoal gray in color and do not appear metallic.
Ceramic magnets are not suited for high-temperature applications (over 250° C)
We stock ceramic ring magnets in Grade 5, magnetized through the thickness. Grade 8 is also available by request; that is generally used in more demanding technical applications.

MPCO specializes in the production of Hard Ferrite (anisotropic) using a wet pressing process. Cutting and grinding of the magnets is performed with an electroplated diamond grinding wheel. Cheap Ferrite Magnet Ceramic Ring C8, Ring Shape Sintered Ferrite Magnet for Speaker
