Low Price Customized High Performance Round Disc Ferrite Big Speaker Magnet
Ferrite magnet or ceramic magnet is the cheapest magnetic material available with the lowest cost/energy ratio, also known as Ceramic Magnets, they are mainly Strontium based (SrFe2O3), manufactured with Strontium Carbonate additive to increase performances from the obsolete Barium based (BaFe2O3). Their good coercive force results from high crystal anisotropy of Strontium iron oxide. However, isotropic parts can also be produced where a simple and easy multi-pole magnetization is required. The most common shapes are simple, such as blocks,cylinders, rings and arcs. Ferrite is not conductive and has high resistance against corrosion, acids, salts, lubricants.
Common direction of magnetization showed in picture bellow:
1> Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametrically.
2> Rectangle shape magnets can be magnetized through Thickness, Length or Width.
3> Arc shape magnets can be magnetized Diametrically, through Width or Thickness.
Special direction of magnetization can be customized as required.
Ferrite (Ceramic) magnets are the lowest cost hard magnets available today, it is a ceramic material made by mixing and firing large proportions of iron oxide (Fe2O3, rust) blended with small proportions of one or more additional metallic elements, such as barium, manganese, nickel, and zinc.They are both electrically non-conductive, meaning that they are insulators, and ferrimagnetic, meaning they can easily be magnetized or attracted to a magnet. Ferrites can be divided into two families based on their resistance to being demagnetized (magnetic coercivity).
Ferrite compounds are extremely low cost, being made of mostly rusted iron (iron oxide), and have excellent corrosion resistance.
They are very stable and difficult to demagnetize, and can be made with both high and low coercive forces.
