Product Details

Permanent Ferrite Round Ring Magnets

Also known as ceramic magnets, ferrite magnets offer excellent value for money when pull strength is not the most important factor. They have a high resistance to corrosion and demagnetization and can operate in temperatures up to 180oC. Ring magnets are made specifically for loudspeaker systems and their sizes have evolved with demand from this market. However, they are also commonly used in magnetic rollers for separating applications and in the printing industry. They are also a vital component found in fast running conveyor systems in many manufacturing plants dealing with ferrous material.

Ferrite, also known as Ceramic Magnets, is made of a composite of Iron oxide and barium carbonate (BaCO3) or strontium carbonate (SrCO3). Since the 1950’s, this material is commonly available and at a lower cost than other types of materials used in permanent magnets. Ceramic magnets are made by pressing and sintering. Sintered magnets are a type of ceramic composed of the compressed powder of the alloy material being used. 



Sintering involves the compaction of fine alloy powder in a dry and then fusing the powder into a solid material with heat. While the sintered magnets are solid, their physical properties are more similar to a ceramic and are easily broken and chipped.
