Ferrite Ring Magnets
The round magnets with a hole in the center are made of SrO or BaO and Fe2O3 by molding and sintering, they are looks like discs and known as ring-shaped permanent ferrite(ceramic) magnets. Ring shape ferrite (ceramic) magnets are axially magnetized, and with magnetic poles on flat surface. Ring-shaped permanent ferrite magnets are carried with anisotropic properties and wide size range from small to large.
Characteristics Of Ferrite Ring Magnets
Magnetic ferrite ringhave 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.
Application Of Permanent Ferrite Magnet Rings
Ferrite magnet rings (also known as ceramic magnet rings) have less energy than other permanent magnet rings, 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.
BeiLun Meank, as an excellent permanent magnet company, offers a wide range of permanent magnet chinafor you to choose from.
