1) low cost
2) hard and brittle
3) require specialized machining techniques
Hard FerriteMagnet:
Ferrite magnet is sintered permanentmagnet composed of barium or strontium ferrite.
This class of magnet, aside fromgood resistance to demagnetization, has the popular advantage oflow cost. Ferrite magnets are very hard and brittle, and requirespecialized machining techniques.
Ferrite magnet has Anisotropic andIsotropic two type.
Anisotropic grades are oriented in themanufacturing direction, and must be magnetized in the direction oforientation. Have grade: Y8T Y10T.Isotropic grades are not orientedand can be magnetized in any direction. Have grade Y25,Y30, Y30BH,Y35.
Ferrite magnets are available invarieties of shapes and sizes, including round disks, rings,blocks, arc segments, u-shapes, cylinders block etc. The finishedproducts could be magnetized or un-magnetized as userspecified.
Because of their low cost, ferritemagnet has a very wide range as well as very large quantity ofapplications, including motors, loudspeakers, toys andcraft.
