What are Ferrite Magnets?

Identifiable by their dark graphite grey colour, Ferrite Magnets or ceramic ferrite magnets, boast inertness corrosion resistance and do not require protective plating. With a reasonable resistance to demagnetisation, these high-temperature resistance magnets can operate in temperatures of up to 180 degrees Celsius.

Ferrite magnets are made from a ceramic compound containing iron oxide combined chemically with either strontium (SrO·6Fe2O3) or barium (BaO·6Fe2O3) most commonly. Although cobalt (CoO·Fe2O3) is sometimes used also.

How Strong Are Ferrite Magnets?

While Ferrite Magnets may not match the strength of Neodymium magnets, they offer excellent magnetic strength and depth of field, especially in larger sizes or volumes. For example, a 75mm x 50mm x 20mm thick ferrite magnet, though weaker than Neodymium magnets, provides substantial clamping force without the risks associated with handling larger, more powerful magnets.

Our thick Y30BH ceramic magnet, measuring 75mm x 50mm x 20mm thick, boasts a maximum pull of 5kg. When used with inexpensive steel poles, it can generate high clamping forces. Consider the example of two steel plates, each 80mm x 60mm x 3mm, placed on either side of the magnet, creating a steel/magnet/steel sandwich. The magnet's pulling capacity jumps to an impressive 50kg due to the concentrated magnetism on the 80 x 3mm edges of the poles.

Applications of Ferrite Magnets

Ferrite magnets find their niche in applications where larger magnets at a lower cost are essential. From powering electronic devices and magnetic separation and detection systems to serving as essential components in automotive applications and energy generation systems, ferrite magnets exhibit remarkable magnetic strength and stability.

Their resilience in challenging environments and ability to withstand high temperatures make them the ideal magnet for commercial industries. The inherent characteristics of ferrite magnets, such as corrosion resistance and longevity, position them as reliable assets for manufacturers seeking robust solutions in motors, sensors, and other precision equipment.
