Product Description

Ferrite Magnets:

1, Material: SrO or BaO and Fe2O3

2, Coating: None or customer request.

3, Grades: Y10t, Y20, Y25, Y30, Y30BH, Y35

4, Ring: We can machining on the basis of customer's specification.

5, Magnetic properties: High corrosion resistance, High working temperature, High coercive force and low cost.

6, Applications: Ferrite magnets are widely used in many fields such as Audio equipment(louder speaker, head set, speaker and etc. ), motors(voice coil motors, stepper motor, Synchronous motors, gear motor, disc-type motors, servo motor), instruments and meter, medical equipment and industry electric drive and control and other fields.

Ferrite magnet is made of SrO or BaO and Fe2O3 by ceramic processing technology. Now we have six grades of permanent magnet products, namely Y10t, Y20, Y25, Y30, Y30BH, Y35. The products appear ring, disk, block, and segment types. We can also make unusual shapes according to customers' requirements, And the shapes can be made by means of molding, cutting, grinding and Drilling. It's manly used in speakers, Motors, etc.
