Product Description

I.Ferrite anisotropic sintered  magnetic rings 

Anisotropic sintered ferrite magnets have higher magnetic properties compare with isotropic ferrite magnet. However,
this type of magnets can only be magnetized along the preferred direction;the sintered Ferrite has an excellent
resistance to demagnetization. 
 
The Polar Anisotropic Ferrite Ring Magnets are the magnets with multipoles in ring shape. They have become the key
component of stepping motors which are widely used in computer peripheral and consumer electronics, such as washing
machine,different types of pumps,  printer and digital -camera,etc.


  
II.Features :

 
Using the latest innovative technologies to make magnetic multi pole rings with high coercive force, strong corrosion
resistance and oxidation resistance. The surface of magnetic flux density has reached 0.2T, Concerning widely
application with large difficulties of 4 poles magnet which density can reach 0.18~0.195T.
 
According to customer's request, good quality with competitive price and best delivery time, one station service.
Guarantee the best price based on the same quality.

III. Manufacturing Process : 



1.Two Manufacturing process :
 
Dry process can produce isotropic & anisotropic magnets, tool can be changed and developed easily.
By wet process, only anisotropic magnets can be produced, it is complicated to change the tool and the tooling charge is much higher.
 
2.Magnetization :
 Isotropic ferrite magnets  are not oriented and can be magnetized in any direction. Anisotropic ferrite magnets are different,
 they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.
