    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.

    Pressing and Sintering:

    Pressing and sintering involve pressing very fine ferrite powder in a die and then sintering this pressed magnet. All fully dense Ferrite magnets are produced this way. Ferrite magnets can be wet pressed or dry pressed. Wet pressing yields better magnetic properties, but poorer physical tolerances. Generally, the powder is dry for grade 1 or 5 materials and wet for grade 8 and higher materials. Sintering involves subjecting the material to high temperatures to fuse the pressed powder together, thus creating a solid material. Magnets produced through this process usually need to have some finish machining, otherwise, surface finishes and tolerances are not acceptable. Some manufacturers extrude instead of press wet powder slurry and then sinter the material. This is sometimes done for arc segment shapes, where the arc cross-section is extruded in long lengths, sintered, and then cut to length.

    Surface Treatments
    The corrosion resistance of Ferrite is considered excellent, and no surface treatments are required. However, Ferrite magnets may have a thin film of fine magnet powder on the surface and for clean, non-contaminated applications, some form of the coating may be required.

    Machining:
    Ferrite is brittle and prone to chipping and cracking. Special machining techniques must be used to machine this material. We are fully equipped to machine these materials to your blueprint specifications. Loud Speaker Ferrite Multipole Ring Magnet

    Magnetizing and Handling:
    Ferrite magnets require magnetizing fields of about 10 kOe. They can be magnetized with multiple poles on one or both pole surfaces. No special handling precautions are required, except that large blocks of Ferrite magnets are powerful, and care should be taken to ensure that they do not snap towards each other. Multipole Ring Ceramic Magnet OD80 x ID40 x T10mm
