Ferrite Ring Magnets

Ferrite ring magnets have excellent corrosion resistance and can be used without electroplating

Ferrite ring magnets are very hard and brittle, easy to break and difficult to process.

The permanent ferrite rings has very good temperature resistance, with relative magnetic stability up to 250 degrees Celsius.

Ferrite ring magnets have greater coercivity and strong resistance to demagnetization.

Ferrite magnet rings (also known as ceramic magnet rings) have less energy than other permanent magnet rings like the China neodymium ring magnet, but advantages of  resistance to demagnetism, corrosion resistance, and low cost make them a popular choice for many projects. Ferrite ring magnets of various sizes are often used in loudspeakers, household appliances, torque drivers and resonance imaging. Holding, closing doors, joinery and lighting fixtures are other applications of permanent ferrite rings.
