Product Description
I. Polar Anisotropic Ferrite Ring Magnets 

Permanent ferrite magnet is made of SrO or BaO and Fe2O3 by ceramic processing technology.
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.

III. Ferrite anisotropic multipole magnet rings       
 
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.
