Detailed Product Description

Feature of Ferrite Magnet/Speaker magnet/ Permanent magnet:

Ferrite Magnet/Speaker magnet/ Ring 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.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.
