Custom made y35 hard ferrite magnet tiles   

1.Introduction

Ferrite magnet tiles are made of hard ferrites, which have a high coercivity and high remanence after magnetization. These are composed of iron oxide and barium or strontium carbonate. The high coercivity means the materials are very resistant to becoming demagnetized, an essential characteristic for a permanent magnet. They also conduct magnetic flux well and have a high magnetic permeability. This enables these so-called ceramic magnets to store stronger magnetic fields than iron itself. They are cheap, and are widely used in household products such as refrigerator magnets. The maximum magnetic field B is about 0.35 tesla and the magnetic field strength H is about 30 to 160 kiloampere turns per meter (400 to 2000 oersteds).The density of ferrite magnets is about 5g/cm3.

 

2.Material of magnet tiles:

Strontium ferrite, SrFe12O19 (SrO·6Fe2O3), a common material for permanent magnet applications.

Barium ferrite, BaFe12O19 (BaO·6Fe2O3), a common material for permanent magnet applications. Barium ferrites are robust ceramics that are generally stable to moisture and corrosion-resistant. They are used in e.g. subwoofer magnets and as a medium for magnetic recording, e.g. on magnetic stripe cards.

Cobalt ferrite, CoFe2O4 (CoO·Fe2O3), used in some media for magnetic recording.

6.Applications of magnet tiles:

barium ferrite magnets are now widely applied in speaker, louderspeaker,Ferrite magnets have largely displaced Alnico magnets in these applications.It is a common magnetic material for electromagnetic instrument pickups.

  • Speaker magnets
  • DC brushless motors
  • Magnetic Resonance Imaging (MRI)
  • Magnetos used on lawnmowers and outboard motors
  • DC permanent magnet motors (used in cars)
  • Separators (separate ferrous material from non-ferrous)
  • Used in magnetic assemblies designed for lifting, holding, retrieving and separating
