Product Description
Features:
1) Low cost
2) High corrosion resistance
3) High working temperature
4) Best choice for industrial application
Industrial Ferrite Magnet:
Ferrite or Ceramic Magnets are still the most widely used magnets with a maximum energy product of 1 to ± 4.3 MGOe.
Due to the environmental requirements which are becoming more stringent barium ferrite has been replaced bystrontium ferrite during the last years.
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 magnets can be supplied both isotropically and anisotropically, they are used in the most divergent products such as loudspeakers, magnetrons, measuring devices, toys, engines, reed contacts etc.
The maximum temperature of use is 225°C depending on the specification, dimensions and system design.
For specifications: See the table below.
The minimum dimension for block magnets is 2 x 2 x 2 mm, whereas the maximum dimension for this type is 270 x 90 x 25.4 mm.
The minimum dimension for disc magnets is D 2 x 1 mm, whereas the maximum dimension for this type is D 156 x 25.
The minimum dimension for ring magnets is D8 x 2.5 x 3 mm, whereas the maximum dimension for this type is D 256 x D* x 25 mm (* inside diameter in consultation).
Applications of Ferrite Magnets:
Used to design tools for holding, separating, retrieving, and lifting;
Micro motors,DC permanent magnet motors(used in car),DC brushless motors;
Separators( separate ferrous materail from non-ferrous);
Loudspeakers, laser beam printer, copying machine, magnetic playset, printed matter, etc.
We are good at manufacturing segment permanent ferrite magnets, with mould pressing and cutting small squares, with good magnetic property and quality which equal to international advanced counterparts.
