Introduce
Sintered Ferrite Magnet Sintered Ferrite Magnet is manufactured from oxide materialby powder metallurgical process. Its advantages include: low cost, excellent corrosion resistance, resistance to be demagnetized etc. The normal working temperature of ferrite magnet is between -40°C and +250°C. It can be magnetized before or after assembly. Generally, sintered ferrite magnet can be machined to regular shapes like segment, blocks, rings and discs etc. The normal grade for sintered Ferrite magnets are Y10T, Y25, Y30, Y30BH, Y35 etc.
