Product Details

Custom Arc Block Ring Disc Shape Permanent Sintered Ferrite Magnet

Product Description

Ferrite magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. This class of

magnets, with good resistance to demagnetization and high working temperature, has the popular

advantage of low cost. There are anisotropic and isotropic Ferrite magnets.

Ferrite cores are used in electronic inductors, transformers, and electromagnets where the high electrical resistance of the ferrite leads to very low eddy current losses. They are commonly seen as a lump in a computer cable, called a ferrite bead, which helps to prevent high frequency electrical noise (radio frequency interference) from exiting or entering the equipment.

Early computer memories stored data in the residual magnetic fields of hard ferrite cores, which were assembled into arrays of core memory. Ferrite powders are used in the coatings of magnetic recording tapes.

Ferrite particles are also used as a component of radar-absorbing materials or coatings used in stealth aircraft and in the absorption tiles lining the rooms used for electromagnetic compatibility measurements. Most common audio magnets, including those used in loudspeakers and electromagnetic instrument pickups, are ferrite magnets. Except for certain "vintage" products, ferrite magnets have largely displaced the more expensive Alnico magnets in these applications. In particular, for hard hexaferrites today the most common uses are still as permanent magnets in refrigerator seal gaskets, microphones and loud speakers, small motors for cordless appliances and in automobile applications.

Ferrite nanoparticles exhibit superparamagnetic properties.

Ferrite magnets Advantage:

1. Ferrite magnets are corrosion free – for long term performance they are superb; if looked after they are capable of exceeding most products life cycles.Ferrite magnets can be used up to +250 degrees C.

2. Ferrite magnets are low cost, particularly in high volume production runs.

3. Ferrite Magnets resist chemical attacks from many of the alkaline solutions, dilute acids, organic solvents, and some hydroxides. They are fine

foruse in salt water conditions .
