product name sintered permanent speaker ferrite magnet  

1.Material: ferrites ,Strontium,etc.

2.Grade: Y25,Y30,Y30BH,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.Isotropic ferrite 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 (1-8 possible)
   8. Grade 8 is the strongest ceramic material available
   9. Tooling can be expensive

5.Ferrite ring  Magnet, we can machining on the basis of customer's specification.

6.Applications: Ferrite magnets are widely used in many fields such as Audio equipment(louder speaker,head  set,speaker  and etc.), motors(voice coil motors,stepper motor, Synchronous motors,gear motor, disc-type motors,  servo motor), instrument and meter,medical equipment and industry electric drive and control and other fields.

Magnetization:

1. Isotropic ferrite 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

These magnets will have approximately 1500 Gauss on each face. Each magnet can support a steel weight of up to 1.2kg vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness to the magnet. Each magnet can also support up to 0.24kgs in a shear position before beginning to slide down a steel surface under the same conditions. These magnets can be fixed in place using Araldite/Loctite and have a maximum operating temperature of 180 degrees C.

All of the N series neodymium Magent has a 8% DISCOUNT.
