Block Ferrite Magnet- Rectangle Ceramic Ferrite Magnet

Large square magnets are used for cleaning and separation applications, while small square magnets are typically used for support purposes in various handicrafts.

Ferrite (Ceramic) magnetic material was the most popular and commonly used magnetic material throughout the world for many decades. Ferrite Permanent Magnets have always ticked a lot of boxes for consumers. The easily recognisable grey, low cost and, unlike the stronger and much more expensive Neodymium Magnet, has a very high oxidation resistance. 

The ceramic nature of Ferrite magnetic products makes them highly resistant to corrosive forces and also heat-tolerant in temperatures up to 250℃ and as low as -40℃. As with other magnetic materials, Ferrite is also a very brittle material and can easily be permanently damaged if impacted by an external force or pressure. 

Hard Ferrite Magnet cannot be screwed, drilled or bent without cracking. To counteract this type of damage and increase their durability, some Permanent Ferrite Magnets are fitted with a steel cover that helps protect the magnet from accidental impact. These Ferrite Pot magnets also produce a slight increase in holding strength compared to a standard, uncovered Permanent Ferrite Magnet. 

The steel casing can also be used as a convenient means to screw or bolt the magnet to another surface so it can be attached to, or removed from, a surface as needed.
