Customized Ferrite Block Magnets

Ferrite is the cheapest magnetic material and has a high corrosion resistance making coating unnecessary. This magnetic material is hard and fragile and must be processed with diamond, preferably when it is not in a magnetic state. Because it might shrink during the sinter process a tolerance of ± 2 % should be taken into account when determining the dimensions. If grinded ± 0.1 mm. Tighter tolerance is available on request. Ferrite rectangular magnets can be supplied both isotropically and anisotropically.

Powerful Permanent Block Ferrite Magnets

Ferrite magnets advantages

Characteristics Compared with neodymium magnets, creamic magnets (or ferrite magnets) have following advantages:

a. Better temperature resistance say. up to 250 celcius degrees;

b. Can be used outside because it is rust-resistant;

c. Much much cheaper, If the size is not an important element, ferrite magnets is the good alternative to neodymium magnets.


Applications

Block Ferrite magnets can be used in a wide range of applications due to their high coercivity and low cost. They also have good machining properies which allows them to be cut into different shapes and sizes. Ferrite magnet has an excellent resistance to demagnetisation/corrosion, however care must be taken when handling the product due to its brittleness.

Common applications include reed switches,loud speakers, security systems,audio and television.
