Ferrite Magnets (Ceramic Magnets) – General Information!
The Ferrite permanent magnet is also known as a Ceramic Magnet and even as hard ferrite magnet. The name is interchangeable but they all refer to exactly the same material type. They are known as Ceramic Magnets because they are electrically insulating. Ferrite permanent magnets exist in two forms – Strontium Ferrite magnets and Barium Ferrite Magnets. The Strontium Ferrite Magnets is the most common.
Ferrite magnets are darker grey in colour and are often referred to as having a “pencil lead” appearance. Anisotropic Ferrite Ring Permanent Magnet
Ferrite / Ceramic permanent magnets are technically known as hard ferrite materials (when exposed to a brief external magnetic field, the material retains magnetism due to having high coercivity, Hc). They are not the same as soft ferrite materials as used in transformer cores (which do not retain magnetism after exposure to a brief magnetic field because soft ferrite materials have low coercivity). The high coercive force of Ferrite Magnets means they are classified as hard materials, like all the other permanent magnets. ndfeb plastic coated hook magnets
Ferrite magnets are extremely popular due to their characteristics. Ferrite magnets are corrosion free – for long term performance they are superb; if looked after they are capable of exceeding most products lifecycles. Ferrite magnets can be used up to +250 degrees C (and in some cases up to +300 deg C). Ferrite magnets are also low cost, particularly in high volume production runs. We offer 30 grades of ferrite permanent magnet.
From this you should be able to determine your Ferrite magnet requirements (or we can help you if you need more assistance). And we can then provide you with a quotation for your magnet specification.
