Permanent ferrite magnet is made of Sro or Bao and Fe2O3 by ceramic processing technology, now, we have 6 models of permanent magnet products, namely Y10T, Y20, Y25, Y30, Y30BH, Y35 and etc. The products include rings, disks, blocks, and segments.
Ferrite magnet is Made by means of powder metallurgy. Its chemical composition: Ba/Sro-Fe2O3.Hard to be de-magnetized, with good anti-corrosion property. The products are make in the shapes of circular, cylinder, square, tile-type. Widely used for magnetic electro-machinery, loudspeaker products, micro electro-machinery, household appliance, electronic acoustics equipment, copycat, magnetic motor equipment, culture and education tools and magnetic treatment equipment.
Hard Ferrite (ceramic) magnets, composed of barium or strontium, were developed in the early 1960's as an alternative to the more expensive metallic magnets.
This class of magnet is very hard, brittle and possesses lower energy characteristics compared to other magnetic materials. However, it is very popular and widely used because of its excellent resistance to demagnetizaion, corrosion, and the advantageous pricing.
Ferrite magnets are manufactured by pressing, sintering, or injection molding. These magnets can be both anisotropic and isotropic. Anisotropic grades are oriented in the manufacturing direction and must be magnetized in the direction of orientation. Isotropic grades are not oriented and can be magnetized in any direction.
Applications: Motors, Meters, Speakers, Sensors, Medical Machine products, Magnetic Sport products, etc
