• Product:
  Ferrite Speaker Ring Magnet
  
  
• Model Number:
  MS005-2
  
  
• Description:
  Sintered ferrite magnet is also called Ceramic magnet. There are mainly two types of ferrite magnets, barium ferrite and strotium ferrite. Since the raw material is very cheap, and the maufacturing process is simple, sintered ferrite magnet is very cheap among all other magnetis material. On the other hand, magnetic properties of sintered ferrite magnet are fairly good, they are widely used in many different application field, such as motor and louderspeakers.
  
  Sintered ferrite magnet is availabe in isotropic and anistropic type. Isotropic ferrite magnet has same magnetic properties in all directions, the strength is lower and can be magnetized in all directions or multi poles. Anisotropic ferrite magnet has better magnetic properties comparing with isotropic ferrite, but this type of magnet can only be magnetized in a prefered direction.
  

  Sintered ferrite magnet can be used at from -40 degree to 200 degree, the mechanical property of ferrite is hard and brittle, they can be cut by diamond tools.

  Since the raw material of ferrite magnet is oxide, it will not be rusted under severe environment not affected by many chemicals(except by some strong acids).
