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.Thenormal 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 gradefor sintered Ferrite magnets are Y10T, Y25,Y30,Y30BH,Y35 etc.

 

 

Typical Applications:

 

*Electric Motors

*Loudspeaker

*Magnetic Knife Holder /Rack

*General Holding Devices and so on
