Sintered Ferrite Radial Ring Anisotropic Magnet Permanent Y28H, Multipole Polar Sintering Ceramic Magnet Rings, Customized radial multipole ferrite magnetic ring, Hard Ferrite Anisotropic Motor Rotor Magnets China Supplier Factory
Sintered Ferrite Radial Ring Anisotropic Magnet Permanent Y28H OD54.5*ID33*H36mm Description
Hard Ferrite magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. This class of magnets has good resistance to demagnetisation and corrosion, Due to their low cost, Ferrite magnets enjoy a very wide range of applications, from motors and loudspeakers to toys and crafts, occupy about 75% of the world market of constant magnets. we can supply you with both wet-pressed anisotropic and dry-pressed isotropic grades in all shapes and sizes.
The Permanent ferrite magnet is made of SrO or BaO and Fe2O3 by ceramic processing technology.The texture is relatively hard, brittle material.According to the different orientation of the crystal , it can be divided into isotropic magnets and anisotropic magnets. Due to the ferrite has good temperature resistance with low cost, which has become one of the most used magnets. Polar Sintered Anisotropic Ferrite Multipole Rings, Sintered Hard Ferrite Magnet Anisotropic Ring Y35, External Radial Multipole Ring Stepper Motor Anisotropic Ferrite Magnet
