  Sintered Ferrite Magnet Block

 Descriptions

 

A low cost alternative to other magnetic materials, offers relatively high operating temperatures and good resistance to corrosion & demagnetization. However, it has lower energy levels (Br) and is brittle in nature.

 

Ferrite magnet block 1) Strong magnetic force  2) High intrinsic coercive force 3) Wide application

 

 

Applications

 

Widely used in many fields, such as Dc motors, Louderspeaks, Magnetic Separators, Automotive Sensors, Educations, etc.
