Detailed Product Description
1. Low cost and low price.
The raw material cost is very cheap and manufacturing process is simply. so the price of it is very low
2. Nice temperature stability
Ferrite magnets can be used between -40oC and +200oC
3. Hard and brittle
They can be cut using diamond tools
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 and loudspeakers.
