Description

Specifications
1.Material: ferrites ,Strontium,etc.

2.Grade: Y*5,Y*0,Y*0BH,etc.

3.Size: It will be different according to client's requirement;

4.Shape: Arc,Tile,Block,Bar,Ring,Cube, Rectangular or others.

5.Application:Widely used in ammeter,speaker,audio,phone,TV,dynamo,etc.

Advantage
1.Cheapest magnet material
2. Good anti-corrosion performance, no surface treatment needed
3.Excellent temperature stability
4.Compact crystal
5.Could provide isotropic and anisotrpic

Two manufacturing Process
1.Dry process:By dry process, can produce isotropic & anisotropic magnets;the tool can be changed and developed easily.
2.Wet process:By wet process, only anisotropic magnets can be produced;it is complicated to change the tool and the tooling charge is much higher

Magnetization
1.Isotropicferrite magnets are not oriented and can be magnetized in any direction;
2.Anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.

Attributes

   1. Least expensive material compared to alnico and rare earth magnets
   2. High intrinsic coercive force
   3. Available in simple shapes only due to manufacturing process
   4. Lower service temperature than alnico, greater than rare earth
   5. Finishing requires diamond cutting or grinding wheel
   6. Lower energy product than alnico and rare earth magnets
   7. Most common grades of ceramic are 1, 5 and 8 (**8 possible)
   8. Grade 8 is the strongest ceramic material available
   9. Tooling can be expensive
