Countersunk Ferrite Pot Magnets

These ferrite pot magnets have countersunk hole of different sizes in the middle to fit different countersunk screws. The steel cup make the countersunk ferrite durable and stronger. The dimension of countersunk ferrite pot magnet varies from 16mm to 63mm. They are known as standard sizes in magnet field. Diameters of 25mm, 32mm, 50mm are the best selling standard countersunk ferrite pot magnets. There are technical details in the following table. For stronger countersunk pot magnet, please look at our neodymium countersunk pot magnets.

Characteristics Of Countersunk Ferrite Pot Magnets

  • Steel house of countersunk ferrite pot magnet are usually plated with blue zinc or bright nickel.

  • Ferrite countersunk pot magnet withstands higher temperature than neodymium.

  • The magnetic material grade of ferrite countersunk pot magnets is ferrite of Y30BH.

  • China countersunk pot magnet of ferrite is much cheaper than the same sized neodymium magnet.
