  • 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 neodymium pot/cup magnet is a magnetic assembly that a disc shape magnet with a countersunk hole housed with a flat steel cup,which are used as holding magnets and mounting magnets.
