Ferrite Magnet

There are mainly two types of ferrite magnets, barium ferrite (BaO.6Fe2O3) and strontium ferrite (SrO.6Fe2O3). Ceramic Magnets offer the best value when comparing cost. They are inexpensive, moderate in magnetic strength, and they are easily magnetized in a variety of formats. Ceramic magnets offer good corrosion resistance and generally do not require a coating or plating, so sintered ferrite magnets widely used in many different applications, such as motors and loudspeakers.
Characteristic of Sintered Ferrite magnet:
1. Low cost and low price.
2. Nice temperature stability
Ferrite magnets can be used between -40oC and +200oC
3. Hard and brittle
4. Well prevent corrosion
The raw material of sintered ferrite magnet is oxide, so ferrite magnets will not be rusted under severe environment nor affected by many chemicals (except some strong acids).
5. Applications for sintered ferrite magnets:
Widely used in many different applications, such as motors, loudspeakers and magnetic toy.
