PRODUCT INFORMATION

No tooling needed, we can cutting it according to your requirement.

Ferrite Magnet is a magnet compounded by magnetic powder and high polymer materials through the special craft.

   It is superior to the sintered magnet in aspects of magnet shaping, size precision, flexibility etc. It may make the handed, circular, various geometric figures, sheet, coiled material (max. Width 780MM, thickness 0. 25-8MM, indefinite length ) according to the consumer’s requirements. Its surface may implement UV oil coating, spray lacquer, printing, lamination, double-faced adhesive tape, PVC processing and so forth. The products are widely applicable for the small-size precise motor, generator etc in aspects of the drive equipments; Loud-speaker, earphone, microphone, sound pick-up etc in aspects of the acoustic facilities; Relay, switch, sensor, instrument and meter and so no in aspects of the communication installation etc. The suction magnet is mainly used for the advertisement propaganda, electric refrigerator door sealing strip, toy and so forth. The correcting magnet is used in TV image tube, magnetic coupler, electronic lock etc.

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.

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 life-cycles. 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 27 grades of ferrite permanent magnet.

FAQ

How do ceramic/ferrite block magnets compare to other types of magnets in terms of strength?

Ceramic/ferrite magnets have lower magnetic energy products compared to rare-earth magnets. However, their magnetic strength is adequate for many applications, especially where the highest magnetic force is not necessary, and cost or environmental resistance is a priority.

Can ceramic/ferrite block magnets be customized in size and shape?

Yes, these magnets can be customized to a wide range of sizes and shapes during the manufacturing process. The mixture of ferrite powder is pressed into molds before being sintered, which sets the final properties. Due to their brittleness, significant modifications after sintering are not recommended, although they can be cut or ground to size with appropriate tools.

How should ceramic/ferrite block magnets be handled and stored?

Handling: Despite their hardness, ferrite magnets are brittle and can chip or break if dropped or knocked together. Care should be taken during handling. Storage: No special requirements are necessary for storing ferrite block magnets. However, they should be stored in a way that prevents strong impacts or pressure that could cause damage.

Are ceramic/ferrite block magnets affected by temperature?

Ceramic/ferrite magnets can withstand high temperatures up to a certain point (typically up to 250°C or 482°F) before experiencing a permanent loss in magnetic properties. They are suitable for most applications where extreme temperatures are not a concern.

How are ceramic/ferrite block magnets manufactured?

The manufacturing process involves mixing ferrite powder with a binder, pressing the mixture into a mold to form the desired shape, and then sintering the pressed shape in a kiln at high temperatures. After sintering, the magnets are magnetized using a strong external magnetic field.

Can ceramic/ferrite block magnets be demagnetized?

While they are resistant to demagnetization, it is possible to demagnetize ceramic/ferrite magnets under extreme conditions, such as exposure to very high temperatures (above their Curie temperature), strong opposing magnetic fields, or physical shock. However, under normal conditions, they maintain their magnetism for a long time.
