The multi-pole 6-pole sintered ferrite ring magnet is a circular magnet with a hole, the grade is Y30, the specific size is 25mm outer diameter, 13mm inner diameter, and 5mm thickness. The direction of magnetization is radial 6 pole, or axial magnetization can be selected. Gauss is less than 2000Gs. Ferrite magnets have no coating, the color is black, and the tolerance is generally ±0.1mm. But sometimes we can strictly control tolerances, if the shape is simple, or if there are special needs.
In general, ferrite magnets do not need to be coated or electroplated to seal, depending on the excellent oxidation resistance and corrosion resistance of ferrite. Moreover, ferrite magnets have good high temperature resistance and can work at a high temperature of 250 ° C without affecting performance. It is a good option to reduce costs. If your magnet strength requirements are less than 2000Gs, ferrite rings are also a good choice. Generally can be widely used in loudspeakers, audio, motors, fans, toys and crafts, is currently the most widely used permanent magnet material.

The magnets with countersunk holes are generally mainly neodymium magnets, mainly because the neodymium material is easy to process and the magnetic force is satisfied. Such ferrite rectangular magnets with (punched) countersunk holes are rare, mainly requiring molds. , If you are interested in this product, you can contact the website customer service or leave a message online....
Ferrite magnets, sometimes referred to as ceramic because of their production process, are the least expensive class of permanent magnet materials. Ferrite magnets became commercially available in the mid 1950’s and has since found its way into countless applications including arc shaped magnets for motors, magnetic chucks and magnetic tools....
