hard Ring shape ferrite speaker magnet

We are the factory of hard ring shape ferrite speaker magnet .

Ferrite speaker magnets are very hard and brittle, consequently machining must be done with a diamond wheel, and is easier when done prior to magnetization. Standard tolerances for Ferrite magnet dimensions are +/-.005" for ground  dimensions and +/- 2% of feature size for as sintered dimensions.   Because of their brittleness these magnets will not withstand impact or flexing. We recommend that they not be used for structural purposes. Ferrite speaker magnets are chemically inert non-conductors,  which is a benefit in many applications. However, this feature does eliminate the use of the  EDM process to produce samples or special shapes.

Ferrite Magnet ,Widely applied to various Speaker, medical apparatus, hardware and toys etc

Feature of Ferrite Magnet: 

     Ferrite magnet is sintered permanent magnet composed of barium or strontium ferrite.

    This class of magnet, aside from good resistance to demagnetization, has the popular advantage of low cost. Ferrite magnets are very hard and brittle, and require specialized machining techniques.

    Ferrite magnet has Anisotropic and Isotropic two type.

    Anisotropic grades are oriented in the manufacturing direction, and must be magnetized in the direction of orientation. Have grade: Y8T Y10T.Isotropic grades are not oriented and can be magnetized in any direction. Have grade Y25,Y30, Y30BH ,Y35.

    Ferrite magnets are available in varieties of shapes and sizes, including round disks, rings, blocks, arc segments, u-shapes, cylinders block etc. The finished products could be magnetized or un-magnetized as user specified.

    Because of their low cost, ferrite magnet has a very wide range as well as very large quantity of applications, including motors, loudspeakers, toys and craft.
