d25mm x 3mm ferrite disc magnet

Hard Sintered Round Ferrite Magnet  

Ferrite Disc Magnet can be fixed in place using adhesive or can be pushed into circular drilled holes in wood or plastic. 

Ferrite as a material has a very good resistance to corrosion and has a high maximum operating temperature making it a very versatile magnetic material. Ferrite disc magnets are commonly used in fridge magnets and for craft making.  

Theworking temperatur of ceramic magnte is between the working temperatures of Sintered Neodymium Magnet and SmCo magnet/AlNiCo magnet. They have lower energy than NdFeB, SmCoand alnico magnets.  

Ceramic Magnet or Hard Ferrite Magnet comes in discs, cylinders, rings, blocks, arcs/segment, ball and ellipses etc. 

Magnetic ceramics, oxide materials that exhibit a certain type of permanent magnetization called ferrimagnetism. Commercially prepared magnetic ceramics are used in a variety of Permanent Magnet, transformer, telecommunications, andinformation recording applications.
