  • Product Detail
  • Technical Specifications
Permanent magnets encased with pot shape steel shells are named cup magnets or pot magnets.According to different magnetic materials,cup (pot) magnets are divied into pot neodymium magnet,pot alnico magnet,pot ferrite magnet.Their magnetic strength and prices will be relatively large differences.

Countersunk hole pot / cup ferrite magnet is a nice magnetic assembly for holding,clamping and mounting,it also called a magnetic holder and holding magnet.

Because of the cheapest price of ferrite(ceramic ) magnets,ferrite counterbore shallow pot magnets are used when you want to save cost and not need strong magnetic force,and this countersunk hole pot ferrite magnet having excellent rust resistance and can withstand temperatures up to 250 ℃.
