Factory supply permanent Y35 Block Ferrite Ceramic Magnet
Ferrite block magnet (Ceramic magnet) is one of the most cost effective magnetic materials. Composed of Barium or Strontium Ferrite, these materials exhibit good resistance to demagnetization, and are the lowest cost materials available today. It has a fair to good resistance toward corrosion and it can operate in moderate heat. Ceramic (Ferrite) magnets have low energy product and they are usually used in assemblies containing mild steel. Sintered Ferrite magnets are hard and brittle and are extensively used in consumer products. You are probably familiar with ferrite magnets, often used on the back of refrigerator magnets.
Attributes of ferrite Magnet:
• Least expensive material compared to alnico and rare earth magnets
• High intrinsic coercive force
• Available in simple shapes only due to manufacturing process
• Lower service temperature than alnico, greater than rare earth
• Lower energy product than alnico and rare earth magnets

Magnetization
1.Isotropic ferrite magnets are not oriented and can be magnetized in any direction;
2.Anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.
Two manufacturing Process
1. Dry process: By dry process, can produce isotropic & anisotropic magnets;the tool can be changed and developed easily.
2. Wet process: By wet process, only anisotropic magnets can be produced;it is complicated to change the tool and the tooling charge is much higher.
Ferrite Magnet Applcation:
The permanent ferrites magnets have character of various specifications, cheapness, etc. They are widely used in very sorts of motors, electro-acoustic, magnetic force machines, duplicators, magnetron fields, household apparatus, magnetic couplings, for sensing, loudspeakers, holding-magnet system, crafts, magnetic therapy, novelties and toys.
