Block?ferrite magnetsNo 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& acute;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 m
