Ceramic Magnet

Ceramic (Hard Ferrite) Magnet

Ceramic Magnet (also known as Hard Ferrite Magnet) is a permanent magnet with iron- oxide (Fe2O3) as their principal component. It is one of the most costs effective magnetic materials manufactured today and is commonly used in loudspeakers.   Our factory has been producing ceramic magnets since 1987 and is ISO9001 certified. We offer a wide range of grades, sizes and shapes.

According to the inner structure of the material, it can be divided into Anisotropic Ferrite Magnet and Isotropic Ferrite Magnet. Anisotropic has an energy density 300% higher than isotropic. There are two types of hard ferrite material, barium ferrite and the higher coercive strontium ferrite.


  • Lower priced but strong
  • Hard and brittle
  • Most common grades are ceramic 1, 5 and 8
  • Corrosion resistant and coating not necessary
  • Lower energy product than alnico and rare earth magnets
  • Hard to demagnetize
  • Maximum operating temperature up to 250°C
