Ferrite magnets belong to the sintered permanent magnetic material, and are made of Barium and strontium. The ferrite magnets have strong anti-magnetic demagnetization performance and low-cost advantage. Ferrite magnets are rigid and brittle, need special machining process. The different magnetism of ferrite magnets takes the manufacture direction to charge the magnetism, while the same magnetism has no direction, so it can charge from any direction. Despite the pressure surface – - often the smallest side of ferrite magnets will find slightly stronger magnetic induction. The magnetic energy range of ferrite magnets is between 1.1MGOe to 4.0MGOe.
As the low cost, ferrite magnets manufacture has broad applications, from the motor, speakers, to toys, arts and crafts, which are currently the most widely used permanent magnet materials.
The dimensional tolerances of ferrite magnets can not exceed the scope of customer requirements. The ferrite magnets should be clean, without debris, magnetic, magnets consistent surface finish on the surface. The ferrite magnets do not allow to exist the spallation, ring crack, crack and so on.
